Albert Barnes Commentary Judges 2:1

"And the angel of Jehovah came up from Gilgal to Bochim. And he said, I made you to go up out of Egypt, and have brought you unto the land which I sware unto your fathers; and I said, I will never break my covenant with you:" — Judges 2:1 (ASV)

The angel of the Lord (not an angel). - The phrase is used nearly 60 times to designate the Angel of God’s presence. See (Genesis 12:7) note. In all cases where “the angel of the Lord” delivers a message, he does it as if God Himself were speaking, without the intervening words Thus saith the Lord, which are used in the case of prophets (Joshua 24:2).

When the host of Israel came up from Gilgal in the plain of Jericho, near the Jordan (Joshua 4:19) to Shiloh and Shechem, in the hill country of Ephraim, the Angel who had been with them at Gilgal (Exodus 23:20–23; Exodus 33:1–4; Joshua 5:10–15) accompanied them. The mention of Gilgal thus fixes the transaction to the period soon after the removal of the camp from Gilgal, and the events recorded in (Judges 1:1–36) (of which those related in Judges 1:1-29 took place before, and those in Judges 1:30-36, just after that removal). It also shows that it was the conduct of the Israelites, recorded in (Judges 1:0) as in (Joshua 16:1–10; Joshua 17:0), which provoked this rebuke.
