Charles Spurgeon Commentary 1 Samuel 2:19-21

"Moreover his mother made him a little robe, and brought it to him from year to year, when she came up with her husband to offer the yearly sacrifice. And Eli blessed Elkanah and his wife, and said, Jehovah give thee seed of this woman for the petition which was asked of Jehovah. And they went unto their own home. And Jehovah visited Hannah, and she conceived, and bare three sons and two daughters. And the child Samuel grew before Jehovah." — 1 Samuel 2:19-21 (ASV)

Moreover his mother made him a little coat, and brought it to him from year to year, when she came up with her husband to offer the yearly sacrifice. And Eli blessed Elkanah and his wife, and said, The LORD give thee seed of this woman for the loan which is lent to the LORD. And they went unto their own home. And the LORD visited Hannah, so that she conceived and bare three sons and two daughters. And the child Samuel grew before the LORD.

She lent one child to the Lord, and she had five others given to her. God always pays good interest on all His loans. He that hath pity upon the poor lendeth unto the Lord. It would be well if more would see how much percent they could get from such a loan as that.
