The Hebrew verb gamal (H1580) carries the sense of dealing out or treating someone in a particular way — either in kindness or retribution. It also means to wean a child, emphasizing completion of a course of action.
Gamal captures the biblical conviction that God repays according to deeds — for blessing and for judgment. The LORD 'deals bountifully' (gamal) with the righteous (Psalm 13:6) and also returns evil deeds on the wicked. Psalm 131:2's weaned child — content and no longer demanding — shows the mature trust that emerges from God's faithful dealing. Gamal spans the full range of God's responsive grace.
