1 Samuel 1:12

“And it came to pass, as she continued praying before the Lord, etc.] Being very earnest and importunate with him to grant her request, and therefore repeated her petition, and prolonged her prayer, being unwilling to let the Lord go, until she had a promise, or some satisfaction, that she should have the thing she liked; some think she continued an hour in prayer: that Eli marked her mouth; observed the motion of her lips, and no doubt her distorted countenance, and uplifted eyes and hands, but chiefly the former; not knowing what the woman was at, and what could be the meaning of such motions.”

“Eli marked her mouth--The suspicion of the aged priest seems to indicate that the vice of intemperance was neither uncommon nor confined to one sex in those times of disorder. This mistaken impression was immediately removed, and, in the words, "God grant," or rather, "will grant," was followed by an invocation which, as Hannah regarded it in the light of a prophecy pointing to the accomplishment of her earnest desire, dispelled her sadness, and filled her with confident hope [Sa1 1:18]. The character and services of the expected child were sufficiently important to make his birth a fit subject for prophecy.”

“Continued - Heb. multiplied to pray. By which it appears that she said much more than is here expressed. And the like you are to judge of the prayers and sermons of other holy persons recorded in scripture, which gives us only the sum and substance of them. This consideration may help us much to understand some passages of the bible. 1 Kings (1 Samuel) 1:13”

“continued praying: Heb. multiplied to pray, Luk 11:8-10, Luk 18:1; Eph 6:18; Col 4:2; Th1 5:17; Jam 5:16 1 Kings (1 Samuel) 1:13”

“But when Hannah prayed much (i.e., a long time) before the Lord, and Eli noticed her mouth, and, as she was praying inwardly, only saw her lips move, but did not hear her voice, he thought she was drunken, and called out to her: "How long dost thou show thyself drunken? put away thy wine from thee," i.e., go away and sleep off thine intoxication (cf. Sa1 25:37). לבּהּ על מדבּרת, lit. speaking to her heart. על is not to be confounded with אל ( Gen 24:45), but has the subordinate idea of a comforting address, as in Gen 34:3, etc. 1 Kings (1 Samuel) 1:15”
