Yet if they shall bethink themselves in the land whither they were carried captives, and repent, and make supplication unto thee in the land of them that carried them captives, saying, We have sinned, and have done perversely, we have committed wickedness;
1 Kings 8:47
Bethink themselves occurs in 1 Kings 8:47 (= 2 Chronicles 6:37), "if they shall bethink themselves. . . , and repent, and make supplication unto thee . . . , saying, We have sinned. . . ."
The phrase is used here in a sense equivalent to "When he came to himself" in the parable of the Prodigal Son (Luke 15:17). One version translates the Hebrew more literally: "If they lay it to heart. . . , and repent, and make supplication to thee. . . , saying, 'We have sinned. . . .'" Other occurrences of the same Hebrew idiom are Deuteronomy 4:39; 30:1; Isaiah 44:19; 46:8; Lamentations 3:21.
