Hear in one of thy cities. The Hebrew phrase, "to hear in" ( שָׁמַע בְּ). has sometimes the meaning of to overhear, as in Genesis 27:5; 1 Samuel 17:28; Job 15:8; sometimes it means simply to hear, as in 2 Samuel 19:36 (35); in Job 26:14, it has the force of to hear of or concerning, though some think this questionable.
This latter is apparently the meaning here: If thou hear concerning any of thy cities, etc. Baying. This introduces what is heard.
