When Israel obeys God, they prosper. This is especially true in the Land of Israel. When they fall, God promises to restore them. Like the Philistines, the nations see this and hate Israel because of God's blessing. Remember what Yeshua said about this.
The Philistines envied God's blessing and feared Isaac, so they sabotaged his wells and made false accusations. (Genesis 26:14) Did you know that the word "Palestinian" comes from the same word as "Philistine": Pelishti? Nothing has changed.
Wells in the Bible are often metaphors for a bloodline. Israel's enemies attack the bloodline through assimilation and violence, they attack the Spirit of God and his Name through false teaching and slander, and they attack the Son through disbelief and distraction.
