πικραίνω

I embitter

Definition

The verb πικραίνω primarily means 'to make bitter' or 'to embitter.' In its active voice, it describes causing bitterness, either literally, as in making water undrinkable (Revelation 8:11), or metaphorically, as in provoking someone to anger or resentment. In its passive voice, it means 'to become bitter,' 'to be embittered,' or 'to grow harsh.' This sense is used in Colossians 3:19, where husbands are commanded not to be harsh or embittered toward their wives. In Revelation 10:9-10, the word is used literally for the bittersweet taste of a scroll.

Biblical Usage

πικραίνω appears four times in the New Testament, exclusively in the later writings of Paul and John. It is used once for ethical instruction in a letter (Colossians 3:19) and three times in the apocalyptic imagery of Revelation (Revelation 8:11; 10:9, 10). In Colossians, it describes a relational attitude (being harsh). In Revelation, it describes a literal, physical property (bitter water, a bittersweet taste) that carries symbolic, prophetic significance.

Etymology

Derived from the adjective πικρός (pikros, G4089), meaning 'bitter,' 'sharp,' or 'harsh.' The verb form πικραίνω means 'to make bitter' or 'to embitter.' This root is also the source of the English word 'picric' (as in picric acid), relating to bitterness. The meaning developed from the literal sense of taste to metaphorical uses describing emotional states and harsh behavior.

Semantic Range

This word highlights important biblical themes. In Colossians 3:19, it touches on the theology of marriage and Christian conduct, warning against a destructive attitude that contradicts Christ-like love. In Revelation, its literal use is deeply theological: the bitter waters (Revelation 8:11) symbolize divine judgment, while the bittersweet scroll (Revelation 10:9-10) symbolizes the dual nature of God's prophetic word—sweet in promise but bitter in the judgment it announces. Understanding this Greek term enriches reading by connecting physical sensation to spiritual reality.

In the ancient world, bitterness was a powerful metaphor for grief, resentment, and poison. Harshness or bitterness in family relationships, as warned against in Colossians, was a recognized social problem. The description of water turning bitter (Revelation 8:11) would immediately evoke the story of Marah in Exodus 15:23, where God made bitter water sweet, connecting John's vision to a foundational narrative of judgment and provision.

πικρός (pikros, G4089) — The adjective meaning 'bitter,' describing a quality rather than an action. χολάω (cholaō, G5520) — Means 'to be angry,' focusing more on the emotional state of anger rather than the causative or relational harshness implied by πικραίνω.
