Verse 15. - And Hagar bare Abram a son: and Abram called his son's name - a peculiarity of the Elohist to assign the naming of a child to the father (Knobel); but the present chapter is usually ascribed to the Jehovist, while the instances in which the name is given by the mother do not always occur in Jehovistic sections (cf. Genesis 30:6, which Tuch imputes to the Elohist) - which Hagar bare, Ishmael - thus acknowledging the truth of Hagar's vision.

16:7-16 Hagar was out of her place, and out of the way of her duty, and going further astray, when the Angel found her. It is a great mercy to be stopped in a sinful way, either by conscience or by providence. Whence comest thou? Consider that thou art running from duty, and the privileges thou wast blest with in Abram's tent. It is good to live in a religious family, which those ought to consider who have this advantage. Whither wilt thou go? Thou art running into sin; if Hagar return to Egypt, she will return to idol gods, and into danger in the wilderness through which she must travel. Recollecting who we are, would often teach us our duty. Inquiring whence we came, would show us our sin and folly. Considering whither we shall go, discovers our danger and misery. And those who leave their space and duty, must hasten their return, how mortifying soever it be. The declaration of the Angel, I will, shows this Angel was the eternal Word and Son of God. Hagar could not but admire the Lord's mercy, and feel, Have I, who am so unworthy, been favoured with a gracious visit from the Lord? She was brought to a better temper, returned, and by her behaviour softened Sarai, and received more gentle treatment. Would that we were always suitably impressed with this thought, Thou God seest me!And Hagar bare Abram a son,.... Being returned to his house, and received by him, and reconciled to Sarai, she brought forth a son to Abram, according to the prediction of the angel:

and Abram called his son's name, which Hagar bare, Ishmael; and this name Jarchi suggests he gave by the inspiration of the Holy Spirit that dwelt in him: but it is highly reasonable to suppose, that Hagar upon her return reported to Abram the whole of the conversation she had with the angel; wherefore Abram believing what she said, in obedience to the order and command of the angel, gave him this name.
