The anger of Yahweh was kindled against Israel, and he sold them into the hand of the Philistines, and into the hand of the children of Ammon.
"The acuter [sic] pressure at this stage came from the Ammonites who were crueller [sic] in nature and more predatory in their methods than the Philistines (cf. 1 Samuel 11:1-2)." [Note: Cundall and Morris, pp. 138-39.]
