Only the Lord establish his word We do not read of any thing the Lord had spoken about this child: but, perhaps Elkanah looked upon what Eli had said as spoken by God, because he was God's high-priest. The Hebrew, however, may be rendered with equal propriety, The Lord establish his work; that is, may he perfect what he hath begun, by making the child grow up, and become fit for God's service, that he may be employed therein and accepted of God. For the word דבר dabar, signifies any matter or thing, as well as word.
