To hear a noise. For similar examples, see on ch. 6:19.
Hath hired. The use of mercenary troops was common in antiquity. The children of Ammon hired the Syrians for resistance against David (2 Sam. 10:6 and 1 Chron. 19:6, 7).

Kings of the Egyptians. This was the time of the Twenty-second Dynasty of Egypt (see on 1 Kings 14:25) when the capital was at Bubastis in the eastern Delta and Egypt was ruled by a dynasty of Lybian kings. The “kings of the Egyptians” undoubtedly refers to certain minor and subsidiary kinglets rather than to the king of Egypt proper.
