Albert Barnes Commentary Judges 13:12

"And Manoah said, Now let thy words come to pass: what shall be the ordering of the child, and [how] shall we do unto him?" — Judges 13:12 (ASV)

This translates to: “What shall be the manner (or ordering) of the child, and what shall be his work (or exploits)?” The original message of the Angel had given information on these two points:

1. how the child was to be brought up, namely, as a Nazarite;
2. what he should do, namely, begin to deliver Israel.

Manoah desires to have the information repeated (compare 1 Samuel 17:26–27 and 1 Samuel 17:30). Accordingly, in Judges 13:13, the Angel refers to, and expands upon, his former instructions.
