C. F. Keil and Franz Delitzsch on 1 Samuel 1:23

1Sa 1:23

Elkanah expressed his approval of Hannah’s decision, and added, “only the Lord establish His word,” i.e., fulfil it. By “His word” we are not to understand some direct revelation from God respecting the birth and destination of Samuel, as the Rabbins suppose, but in all probability the word of Eli the high priest to Hannah, “The God of Israel grant thy petition” (1Sa 1:17), which might be regarded by the parents of Samuel after his birth as a promise from Jehovah himself, and therefore might naturally excite the wish and suggest the prayer that the Lord would graciously fulfil the further hopes, which the parents cherished in relation to the son whom they had dedicated to the Lord by a vow. The paraphrase of דּברו in the rendering given by the lxx, τὸ ἐξελθὸν ὲκ τοῦ στόματός σου, is the subjective view of the translator himself, and does not warrant an emendation of the original text.
