New Defender's Study Bible Notes
3:16 from the city Adam. The towns of Adam and Zaretan were near the confluence of the rivers Jabbok and Jordan, some fifteen miles north of the Dead Sea. This long stretch of dry river bed provided ample room for the Israelites to cross over Jordan. This verse should be understood in the sense “an heap very far away, at the city Adam.”
3:17 passed clean over Jordan. In addition to this occasion, the Jordan was later stopped on two other occasions. See II Kings 2:8, 14. Only a small passageway was needed on these occasions for Elijah and Elisha to cross, but these also required God’s miraculous intervention.
