What it means
(Qal) to abstain from food, fast
Abridged from Brown, Driver and Briggs, A Hebrew and English Lexicon of the Old Testament (1906), via STEPBible.org (CC BY 4.0).
In depth
From the study of Nehemiah 1:4
- Range of meaning
To abstain from food (sometimes also drink), as an act of mourning, humbling oneself, penitence, or urgent petition to God.
- Against the English
"Fast" is accurate. What English readers may miss is that in this period fasting was tied specifically to mourning for Jerusalem.
- Used elsewhere in the period
After the exile the Judeans kept fasts marking the fall of Jerusalem and the temple (Zech 7:3–5; 8:19: the fasts of the fourth, fifth, seventh and tenth months). Fasting joined to prayer at moments of national crisis: Ezra 8:21–23; Esther 4:3, 16; Dan 9:3 ("with fasting, sackcloth and ashes"); Joel 2:12.
From the study of 2 Samuel 12:16
- Range of meaning
Tsum means going without food, and often without drink too, usually from sunrise to sunset or for set days. In Israel and the wider ancient Near East, fasting was a way of making oneself low. People fasted when they mourned (1 Sam 31:13; 2 Sam 1:12), repented (1 Kgs 21:27; Jonah 3:5), pleaded with God in a crisis (Judg 20:26; Esth 4:16) and kept the Day of Atonement, described as "afflicting yourselves" (Lev 16:29).
- Against the English
"Fasted" is accurate. Only the doubled "fasted a fast" disappears in English; it stresses that this was a deliberate, real fast.
- How it drifted
Today "fasting" is often understood as a personal discipline for spiritual growth, or as a health or diet practice. In this text it is a public sign of humbling oneself before God, done together with lying on the ground and, in some manuscripts, sackcloth.
- Used elsewhere in the period
Ps 35:13 links fasting, sackcloth and pleading for someone who is sick. Joel 1:13–14 and Jonah 3:5–9 show fasting and sackcloth used together to try to turn God from a judgment he has announced ("Who knows? God may turn," Jonah 3:9; Joel 2:14). David says almost exactly this in v.22.
From the study of 1 Samuel 7:6
- Range of meaning
To fast: to go without food, usually for a day, usually in public, as part of mourning, pleading with God, or repenting in a time of danger. Often paired with weeping, sackcloth, ashes and confession (Judg 20:26; 2 Sam 12:16; Joel 2:12; Neh 9:1–2).
- Against the English
'Fasted' is accurate. A modern reader may picture a private spiritual discipline or a health practice. Here it is a whole nation abasing itself together.
- Used elsewhere in the period
Israel fasts at Bethel before the LORD in a war crisis (Judg 20:26). Later the Torah's command to 'afflict yourselves' on the Day of Atonement was understood as fasting (Lev 16:29). National fasts with confession appear in Neh 9 and Joel 1–2.

-
Ezra 8:23 וַנָּצ֛וּמָה and we fasted !

Here: "So we fasted": the whole company went without food. Verse 21 explains what the fast was for: "to humble ourselves before our God." It was a shared act of lowering themselves, not a private discipline. The extra -ah ending is a stylistic habit of late Hebrew narrative (Ezra uses it repeatedly, e.g. v.24 "I set apart") and does not change the meaning.

Here: A plural command. Going without food as a group was the recognised way to mourn and to plead in a crisis. It continues the fasting already under way in 4:3.
