Ahaz was threatened on all sides, on the north by Rezin and Pekah; on the southeast by Edom 2 Chronicles 28:17; and on the southwest by the Philistines 2 Chronicles 28:18. To these external dangers was added the still greater peril of disaffection at home. A large party in Judah was “weary” of the house of David Isaiah 7:13, ready to join the confederacy Isaiah 8:6, Isaiah 8:12, and to accept for king “the son of Tabeal.” Ahaz saw no hope of safety unless he could obtain a powerful protector; and, Egypt being particularly weak at this time, he turned to Assyria.
