יַבֹּק Jabbok, pr.n. of a stream Mount Gilead, on the northern border of the Ammonites, flowing into Jordan on the east, now called وادى زرقا Wady Zŭrka, i.e. blue river, Numbers 21:24; Genesis 32:23; Deuteronomy 2:37, 3:16 Joshua 12:2; Judges 11:13. See Burckhardt’s Travels in Syria, p. 598; Germ. trans.; and my note on the place, in which I have rejected the error of Pococke and others, who confounded this stream with the Hieromiax (Arab. يرموك). As to the etymology, Jo. Simonis, in Ohomast. page 315, is not amiss in deriving יַבֹּק from בָּקַק to empty, by a Chaldaism, for יָבֹק; hence pouring out, emptying; Genesis 32:25, this name is however so alluded to as if it were for יְאַבּוֹק from the root אָבַק.
