1 Samuel 1:10

She was in bitterness of soul Oppressed with grief, which returned when she was alone, and thought of her barrenness, which made her pray, with many tears, for a child. They had newly offered their peace- offerings, to obtain the favour of God; and in token of their communion with him, they had feasted upon the sacrifice: and now it was proper to put up her prayer, in virtue of the sacrifice. For the peace-offerings typified Christ's mediation, as well as the sin-offerings: since by this not only atonement is made for sin, but an answer to our prayers obtained.
