The angel of Yahweh said to Manoah, Though you detain me, I won't eat of your bread; and if you will make ready a burnt offering, you must offer it to Yahweh. For Manoah didn't know that he was the angel of Yahweh.
The translation "again did" in Judges 13:1 implies that the Philistine oppression followed the Ammonite oppression chronologically. However, the Hebrew idiom these words translate does not necessarily mean that. It can also mean, and in view of Judges 10:6-7 must mean, the Israelites "continued to do" evil. The Philistines and the Ammonites began oppressing Israel at approximately the same time (ca. 1124-1123 B.C.). [Note: See Robert G. Boling, Judges, p. 85.]
