2 Samuel 22:27

With the pure thou wilt shew thyself pure; and with the froward thou wilt shew thyself unsavoury.

This verse belongs to a song composed while Saul was pursuing David to kill him. The song arose from severe trials in which David trusted God, recounts his dangers and deliverances through God's providential preservation, and praises God as his merciful preserver. Songs from this early period of David's life express devotion, holiness, and integrity of heart.

In its immediate context, the verse is part of David's testimony that God rewards righteousness and that David kept God's judgments and statutes in view. It teaches that God deals with people according to their moral character: He shows Himself pure toward the pure, while toward the froward He appears displeasing and unsavory and acts in opposition and adversely.

Applied to service, this means God responds favorably to humble, trusting service marked by thankfulness and joy, rather than to a spirit focused on demanding wages.
