In depth
From the study of Matthew 21:25
- Range of meaning
To reckon, consider, deliberate, discuss, argue. In the Gospels it often means inner or group reasoning that is shown to be faulty.
- Against the English
'Reasoned with themselves' (KJV) and 'deliberated among themselves' (BSB) are both fine. The English loses the imperfect tense, which shows the debate as drawn out.
- Used elsewhere in the period
Matt 16:7–8, where the disciples 'reasoned among themselves' about bread and misread Jesus; Mark 2:6–8, where the scribes 'reasoning in their hearts' are read by Jesus; Luke 12:17, where the rich fool 'reasoned within himself'.
- Range of meaning
To reason or think something through; to weigh or ponder; to debate or discuss, either inwardly with oneself or with others. In the Gospels it often describes puzzled, doubting or hostile inner debate (Mark 8:16–17; Luke 3:15; 20:14).
- Against the English
KJV and YLT say "reason ye", WEB "are you reasoning", BSB "are you thinking". Some modern versions have "question" (ESV, NLT), which brings out the note of objection. "Thinking" is the flattest choice.
- How it drifted
Today "reasoning" sounds like calm, logical thinking. KJV's "What reason ye?" can sound neutral or even approving. The Greek word is neutral in itself, but here, as often in the Gospels, it means turning over an objection with suspicion.
- Used elsewhere in the period
Luke 12:17 is a close parallel in form: the rich fool "dialogizeto within himself, saying ...". This shows Luke can say "reasoned ... saying" for a purely inward monologue, which bears on 5:21. Luke 1:29 (Mary "pondered") shows the word can also be neutral.
- Range of meaning
To think something through, deliberate, debate, discuss. It can be neutral, but in the Gospels it often describes anxious, suspicious or hostile calculation.
- Against the English
KJV/WEB 'reasoned among themselves'. BSB 'discussed it among themselves'. ESV gives only 'said to themselves'. NIV 'talked the matter over'. Shortened renderings lose the sense of a deliberate conspiracy.
- Used elsewhere in the period
Luke 5:21–22, where scribes and Pharisees 'reason' against Jesus; 12:17, the rich fool 'reasoned within himself' about storing his goods; 3:15. In 20:5 the chief priests and scribes 'reasoned together among themselves' (a related verb) about how to answer Jesus.
Where it appears
Matthew · 3
-
Matthew 16:7 διελογίζοντο they were reasoning
They discussed this among themselves and concluded, “It is because we did not bring any bread.”
Here: The imperfect tense pictures a discussion that kept going: "they were talking it over" or "they began debating". In the Gospels this verb usually describes people puzzling over something and getting it wrong, or questioning in a muddled or suspicious way. It is not careful logic.
-
Matthew 16:8 διαλογίζεσθε reason you
Aware of their conversation, Jesus said, “You of little faith, why are you debating among yourselves about having no bread?
Here: "Are you reasoning it over / debating". The present tense pictures a discussion still going on. It picks up the same verb from v. 7. In the Gospels this verb often describes human reasoning that has gone down the wrong track (Mark 2:6–8; Luke 5:21–22).
-
Matthew 21:25 διελογίζοντο they were reasoning
What was the source of John’s baptism? Was it from heaven or from men?” They deliberated among themselves and said, “If we say, ‘From heaven,’ He will ask, ‘Why then did you not believe him?’
Here: In the imperfect tense, which pictures ongoing action: 'they were working it through'. They are calculating, weighing what each answer will cost them, not asking what is true.
Mark · 7
-
Mark 2:6 διαλογιζόμενοι reasoning
But some of the scribes were sitting there and thinking in their hearts,
Here: Working the matter over, weighing arguments to reach a verdict. The present tense shows it still going on. In Mark this verb always marks reasoning that is going wrong or missing the point.
-
Mark 2:8 διαλογίζονται διαλογίζεσθε are reasoning, reason you
At once Jesus knew in His spirit that they were thinking this way within themselves. “Why are you thinking these things in your hearts?” He asked.
Here: Present tense: 'they are reasoning'. It means turning a matter over and arguing a case, here a silent legal verdict of blasphemy. It is more than a passing thought.
-
Mark 8:16 διελογίζοντο they were reasoning
So they began to discuss with one another the fact that they had no bread.
-
Mark 8:17 διαλογίζεσθε reason you
Aware of their conversation, Jesus asked them, “Why are you debating about having no bread? Do you still not see or understand? Do you have such hard hearts?
Here: 'Are you going back and forth about…' The present tense pictures a discussion still going on. In Mark this verb usually describes worried or suspicious reasoning that misses the point (2:6, 8; 11:31).
-
Mark 9:33 διελογίζεσθε; were you discussing?
Then they came to Capernaum. While Jesus was in the house, He asked them, “What were you discussing on the way?”
Here: 'Were you talking it through / debating?' The past tense here (the imperfect) shows talk that went on for some time on the road. On its own the verb can be neutral, but v. 34 shows it was a status argument.
-
Mark 11:31 διελογίζοντο they were reasoning
They deliberated among themselves what they should answer: “If we say, ‘From heaven,’ He will ask, ‘Why then did you not believe him?’
Luke · 6
-
Luke 1:29 διελογίζετο was pondering
Mary was greatly troubled at his words and wondered what kind of greeting this might be.
-
Luke 3:15 διαλογιζομένων wondering
The people were waiting expectantly and were all wondering in their hearts if John could be the Christ.
-
Luke 5:21 διαλογίζεσθαι to reason
But the scribes and Pharisees began thinking to themselves, “Who is this man who speaks blasphemy? Who can forgive sins but God alone?”
-
Luke 5:22 διαλογίζεσθε reason you
Knowing what they were thinking, Jesus replied, “Why are you thinking these things in your hearts?
Here: "Are you reasoning / debating." The present tense shows an argument still going on inside them. Jesus repeats the verb Luke used for them in v. 21, so he is naming exactly what they were doing.
-
Luke 12:17 διελογίζετο he was reasoning
So he thought to himself, ‘What shall I do, since I have nowhere to store my crops?’
Here: An ongoing inner weighing-up: 'he kept turning it over.' The past tense used here pictures the process as it unfolds. In Luke the verb often marks inner reasoning that goes the wrong way (5:21–22; 20:14).
-
Luke 20:14 διελογίζοντο were reasoning
But when the tenants saw the son, they discussed it among themselves and said, ‘This is the heir. Let us kill him, and the inheritance will be ours.’
Here: The verb form describes a discussion that went on for a while. In Luke this verb often marks hostile or anxious inner calculation (5:21–22; 12:17), and it echoes the leaders' own huddle in 20:5.
