Now, O king, come down whenever your soul desires, and we will be responsible for delivering him into your hand.”
Here, 1. The Ziphites offer their service to Saul, to betray David to him, Sa1 23:19, Sa1 23:20. He was sheltering himself in the wilderness of Ziph (Sa1 23:14, Sa1 23:15), putting the more confidence in the people of that country because they were of his own tribe.
Commenting on 1 Samuel 23:19-29
Now therefore, O king, come down,.... From Gibeah to Ziph, and the wilderness of it, where David was: according to all the desires of thy soul to come down; to seize such a prey which he was greatly desirous of, and of nothing more so than of that according to Abarbinel, the sense is, that the thing was ready in whatever way he should desire...
1Sa 23:18-20 After these encouraging words, they two made a covenant before Jehovah: i.e., they renewed the covenant which they had already made by another solemn oath; after which Jonathan returned home, but David remained in the wood. The treachery of the Ziphites forms a striking contrast to Jonathan’s treatment of David.
