John Wesley on 1 Samuel 1:28

Lent him - But not with a purpose to require him again. Whatever we give to God, may upon this account be said to be lent to him, that tho' we may not recall it, yet he will certainly repay it, to our unspeakable advantage. He worshipped - Not Eli, but young Samuel, who is spoken of in this and the foregoing verse, and who was capable of worshipping God in some sort, at least with external adoration.
