1 Samuel 7:9

And Samuel took a sucking lamb
Which it might be, and yet more than eight days old, for under that it might not be sacrificed, ( Exodus 22:30 )

and offered it for a burnt offering wholly unto the Lord;
the whole of it was burnt, skin and all, whereas the skin was the priest's in other burnt offerings; and this is remarked ^F13 as one of the three things in which it differed from other offerings; the word being feminine, the Jews gather from hence, as Jarchi notes, that females might be offered at a private altar:

and Samuel cried unto the Lord for Israel;
not only offered a sacrifice for them, but prayed for them:

and the Lord heard him;
and answered him, either by causing fire to come down on the sacrifice, by which it was consumed, or by the voice of thunder, which frightened and discomfited the Philistines; and the event of things manifestly showed it.
