Though Coniah, &c.— Houbigant reads Jeconiah instead of Coniah, See the note on Jeremiah 22:11. The expression though he were the signet, &c. is proverbial, and signifies, "Though he were most dear and valuable to me, yet would I not spare him, on account of his iniquity." See Haggai 2:23. The ring was frequently worn in ancient days as a mark of sovereignty. When Alexander died, he gave his ring to Perdiccas, thus as it were marking him out for a successor.
