“Prayer is, then, to speak more boldly, converse with God. Though whispering, consequently, and not opening the lips, we speak in silence, yet we cry inwardly. For God hears continually all the inward converse. So also we raise the head and lift the hands to heaven, and set the feet in motion at the closing utterance of the prayer, following the eagerness of the spirit directed towards the intellectual essence; and endeavouring to abstract the body from the earth, along with the discourse, raising the soul aloft, winged with longing for better things, we compel it to advance to the region of holiness, magnanimously despising the chain of the flesh.”

“This Hannah does in the first book of Kings [Samuel], portraying a type of the church, [she] prays to God not with a noisy petition but silently and modestly within the very recesses of her heart. She spoke with a hidden prayer but with manifest faith. She did not speak with the voice but with the heart, because she knew that so the Lord hears, and she effectually obtained what she sought, because she asked with faith. Divine Scripture declares this, saying, "She spoke in her heart and her lips moved, but her voice was not heard, and the Lord heard her."”

“Let the virgins likewise form a separate band, singing hymns or reading; silently, however, so that while their lips speak, no other's ears may hear what they say. For, "I suffer not a woman to speak in church." Let the married woman imitate them: let her pray and her lips move but her voice not be heard. So shall Samuel come among us: your barren soul, that is to say, shall bring forth the salvation of "God who has heard your prayers." For that is the meaning of "Samuel."”

“For I seek those tears which are shed not for display but in compunction; those which trickle down secretly and in closets and in sight of no person, softly and noiselessly; those which arise from a certain depth of mind, those shed in anguish and in sorrow, those which are for God alone. Such were Hannah's, for "her lips moved," it is said, "but her voice was not heard." Her tears alone uttered a cry more clear than any trumpet. And because of this, God also opened her womb and made the hard rock a fruitful field.”

“At home her rival mocked her. She went into the temple, and the priest's boy abused her and the priest upbraided her. She fled the storm at home, entered port and still ran into turbulence. She went to get a remedy, and not only did not get it but received an additional burden of taunts, and the wound instead was opened up again. You are aware, of course, how distressed souls are susceptible to abuse and insult: just as bad wounds cannot stand the slightest contact with the hand but become worse, so too the soul that is disturbed and upset has problems with everything and is stung by a chance remark. The woman, on the contrary, was not like that, even in this case with the boy abusing her. Had the priest been intoxicated, the insults would not have been so surprising; his high rank and heavy responsibility convinced her against her will to keep her composure. But in fact she was not even upset with the priest's boy, and hence she won God's favor even further. Should we too be abused and suffer countless misadventures, let us put up nobly with those who insult us, and we shall thus win greater favor from God.”

“But observe even after this her deep reverence. "Only her lips moved, but her voice," it says, "was not heard." And in this way does the one who would gain his request draw near to God; not consulting his ease, nor gaping, nor lounging, nor scratching his head, nor with utter listlessness. So was not God able to grant, even without any prayer at all? So did he not know the woman's desire even before she asked? And yet had he granted it before she asked, then the woman's earnestness would not have been shown, her virtue would not have been made manifest, she would not have gained so great a reward. So that the delay is not the result of envy or of witchcraft but of providential kindness. When therefore you hear the Scripture saying that "the Lord had shut up her womb" and that "her rival deeply provoked her," consider that it is his intention to prove the woman's seriousness. For observe that she had a husband devoted to her, for he said, "Am I not better to you than ten sons?" "And her rival," it says, "deeply provoked her," that is, reproached her, insulted her. And yet she never once retaliated, nor uttered imprecation against her, nor said, "Avenge me, for my rival reviles me." The other had children, but this woman had her husband's love to make amends. With this at least he even consoled her, saying, "Am I not better to you than ten sons?"But let us look again at the deep wisdom of this woman. "And Eli," it says, "thought she was drunk." Yet observe what she says to him also, "No, do not count your handmaid for a daughter of Belial, for out of the abundance of my complaint and my provocation have I spoken up till now." Here is truly the proof of a contrite heart, when we are not angry with those that revile us, when we are not indignant against them, when we reply only in self-defense. Nothing renders the heart so wise as affliction; nothing is there so sweet as "godly mourning."”

“Now Hannah, she spake in her heart,.... It was mental prayer she used, some ejaculations of her mind she sent up to God, which she was sensible were well known to him, and she needed not to express vocally: only her lips moved; as her heart spoke, and sent up her petitions, as if she had used words and phrases in form: but her voice was not heard: that she might not seem to be ostentatious in her prayer, and that she might not interrupt others in their devotions; and she knew that her voice was not necessary with respect to God: therefore Eli thought she had been drunken; by the motions she made, and gestures she used, as if she was muttering something to herself, and by her long continuance therein, and it being after a feast she had been at with her husband, and the rest of the family; from all which Eli concluded this must be her case.”

“Spake in her heart; only her lips moved - She prayed; her whole heart was engaged: and though she spake not with an audible voice, yet her lips formed themselves according to the pronunciation of the words which her heart uttered.”
