Samuel's preparation for intercessory prayer, namely, the offering up an atoning sacrifice, is most significant (compare Luke 1:9-10). The term here used for a "lamb" does not occur in the Pentateuch; indeed it is only found besides this place in Isaiah 65:25. The offering is in accordance with Leviticus 22:27.

The Lord heard him - Better as in margin. The "answer" was not simply the granting the asked-for deliverance, but the great thunder 1 Samuel 7:10, which was "the voice of the Lord," the same voice with which the Lord answered Moses Exodus 19:19; Psalm 99:6.

Samuel took a sucking lamb - This sucking lamb must have been eight days under its mother before it could be offered, as the law says, Leviticus 22:27.

Though Samuel was not a priest, yet he offered this sacrifice; or he might have ordered Eleazar to offer it, and still be said to have done it himself: Qui facit per alterum, facit per se; "He who procures a thing to be done, may be said to do it himself." His not sacrificing at the tabernacle was justified by the necessity of the case; neither tabernacle nor ark was at hand.

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 (m) 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.

(m) Midrash Schemuel apud Abarbinel in loc.

And Samuel took a sucking lamb, and offered it for a burnt offering wholly unto the LORD: and Samuel cried unto the LORD for Israel; and the LORD heard him.

7:9 Cried - And he cried unto the Lord. He made intercession with the sacrifice. So Christ intercedes in virtue of his satisfaction. And in all our prayers we must have an eye to his great oblation, depending on him for audience and acceptance.

heard: or, answered

7:7-12 The Philistines invaded Israel. When sinners begin to repent and reform, they must expect that Satan will muster all his force against them, and set his instruments at work to the utmost, to oppose and discourage them. The Israelites earnestly beg Samuel to pray for them. Oh what a comfort it is to all believers, that our great Intercessor above never ceases, is never silent! for he always appears in the presence of God for us. Samuel's sacrifice, without his prayer, had been an empty shadow. God gave a gracious answer. And Samuel erected a memorial of this victory, to the glory of God, and to encourage Israel. Through successive generations, the church of God has had cause to set up Eben-ezers for renewed deliverances; neither outward persecutions nor inward corruptions have prevailed against her, because hitherto the Lord hath helped her: and he will help, even to the end of the world.
