when God had shut up her womb, and her adversary upbraided her with it, and provoked and fretted her; and when she was so full of grief, that she could not eat her food, and prayed in the bitterness of her soul; but now she could lift up her horn and her head, as horned creatures, to whom the allusion is, do, when they are lively and strong; now she could look pleasant and cheerful, and even triumph, being raised to an high estate, and greatly favoured of the Lord, to whom she ascribes this change of her state and circumstances: it was owing to his power and grace that she was thus strengthened and exalted; as it is owing to the same, that the people of God, who are in a low estate by nature, are raised out of it in conversion, and brought into an open state of grace and favour with God, and put into the possession of rich blessings and mercies, and have hope of eternal glory, on account of which they can exult and triumph:my mouth is enlarged over mine enemies; meaning Peninnah, and those that provoked her, and upbraided her with her barrenness, to whom she was not able to make any reply; but now her mouth was opened, and she could speak largely, and did; not in a way of reproach and reviling, in retaliation for what she had met with from others; but in prayer to God, to whom she could come with open mouth, and use freedom and boldness, and plead with importunity, fervency, and in faith, and in praise and thanksgiving to him for the great and good things he had done for her, and would now freely and largely speak of them to others; to some, her friends, to their joy and pleasure; and to others, her enemies, to their grief and confusion:because I rejoice in thy salvation; not only in temporal salvation wrought by the Lord for her, whereby she was delivered from the reproach of barrenness, through a son being given unto her; but in spiritual and eternal salvation, through the Messiah, she had knowledge of, and faith in, as appears from 1Sa 2:10, as all believers in him do, as it is contrived by the wisdom of God, wrought out by Christ, and applied by his Spirit; it being so great, so suitable, so perfect and complete, entirely free, and of an everlasting duration; see Ps 20:5.
