ἐξομολογέομαι

Matthew 3:6 ἐξομολογούμενοι confessing

Confessing their sins, they were baptized by him in the Jordan River.

Here: Present middle participle: "as they were openly acknowledging". The confession goes along with the immersion. The prefix ex- ("out") points to saying it out loud and in public, not an inner admission. The supplied root gloss "to agree" reflects the base verb homologeō ("say the same thing"). Here the sense is clearly confessing.

Matthew 11:25 ἐξομολογοῦμαί I fully consent

At that time Jesus declared, “I praise You, Father, Lord of heaven and earth, because You have hidden these things from the wise and learned, and revealed them to little children.

Here: An open, spoken acknowledgment of God: praise and thanks that say aloud what God has done. This is the word the Greek Psalms use for "I will give thanks to you."

Mark 1:5 ἐξομολογούμενοι confessing

People went out to him from all of Jerusalem and the countryside of Judea. Confessing their sins, they were baptized by him in the Jordan River.

Luke 10:21 ἐξομολογοῦμαί I fully consent

At that time Jesus rejoiced in the Holy Spirit and declared, “I praise You, Father, Lord of heaven and earth, because You have hidden these things from the wise and learned, and revealed them to little children. Yes, Father, for this was well-pleasing in Your sight.

Here: The standard Greek Bible word for the Hebrew “I give thanks / I praise” (hôdâ): openly declaring what God has done. Here it is praise, not confessing sin and not simply “agreeing”.

Luke 22:6 ἐξωμολόγησεν he promised

Judas consented, and began to look for an opportunity to betray Jesus to them in the absence of a crowd.

Here: 'He agreed' or 'he gave his word'. The verb has the idea of saying something out loud, so it suggests a stated, binding acceptance of the deal, not just a private nod. This is the only place in the New Testament where it is used in this active form and in this sense.

Acts 19:18 ἐξομολογούμενοι confessing

Many who had believed now came forward, confessing and disclosing their deeds.

Here: To admit something out loud and in public. The prefix ex- ("out") strengthens the idea of open, full admission. Here they were admitting what they had done, before the community and probably before outsiders too (compare v. 19, "in front of everyone").

Romans 14:11 ἐξομολογήσεται will confess

It is written: “As surely as I live, says the Lord, every knee will bow before Me; every tongue will confess to God.”

Here: 'Will openly acknowledge.' With 'to God' following, this is the Greek Old Testament's usual phrase for publicly acknowledging and praising God. It is a declaration of who God is, not mainly an admission of sins.

Romans 15:9 ἐξομολογήσομαί I will praise

so that the Gentiles may glorify God for His mercy. As it is written: “Therefore I will praise You among the Gentiles; I will sing hymns to Your name.”

Here: "I will openly acknowledge you with thanks." This is the Greek scripture's word for Hebrew hodah, public thanksgiving and praise. It has nothing to do with confessing sin here.

Philippians 2:11 ἐξομολογήσηται may confess

and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.

Here: To declare out loud and in public that something is true, often in praise. This is the word of Isaiah 45:23 in the Greek Old Testament. The aorist form presents the acknowledgment as one complete act, and the subjunctive marks it as the goal of God's exaltation of Jesus (v. 9: "therefore God exalted him… so that…").

James 5:16 ἐξομολογεῖσθε do confess

Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man has great power to prevail.

Here: A present-tense command, so it describes an ongoing habit: 'keep acknowledging openly'. The prefix ex- ('out') points to saying it out loud to someone, not only admitting it inwardly.
