Judges 3:15-23 - “Again the Israelites cried out to the Lord, and he gave them a deliverer-Ehud, a left-handed man, the son of Gera the Benjamite. The Israelites sent him with tribute to Eglon king of Moab. Now Ehud had made a double-edged sword about a foot and a half long, which he strapped to his right thigh under his clothing…”
Every time the Israelites fell away from the Lord, the enemies rose up against them and prevailed over them. In anguish and affliction they would seek God, who would bless them, but not without their first having reconciliation, a renewal of the Covenant that had been made beforehand. In this passage of Judges, Israel found itself in exactly this situation. They pleaded once more, and the Lord raised up a deliverer for them.
