though there was, no doubt, a peculiar providence which attended the birth of our Lord, and makes this expression more peculiarly applicable to him; since his mother Mary, when her full time was come, was at a distance from the place of her residence, was in an inn, and in a stable there, there being no room for her in the inn, and so very probably had no women about her to assist her, nor any midwife with her; and there was the more visible appearance of the hand of God in this affair, who might truly be said to take him out of the womb:thou didst make me hope [when I was] upon my mother's breasts; which may be understood of the expectation and hope, common to infants, which have not the use of reason, with all creatures, whose eyes wait upon the Lord, and he gives them their meat in due season; and here may regard the sudden and suitable provision of milk in the mother's breast, to which there is in the infant a natural desire, and an hope and expectation of.
The words may be rendered, as they are by some, "thou didst keep me in safety", or make me safe and secure , when I was "upon my mother's breast": this was verified in Christ at the time Herod sought to take away his life; he was then in his mother's arms, and sucked at her breast; when the Lord in a dream acquainted Joseph with Herod's design, and directed him to flee with the young child and his mother into Egypt, where they were kept in safety till the death of Herod.
