Genesis 16:11

11.And shalt bear a son. The angel explains what he had briefly said respecting her seed; namely, that it should not be capable of being numbered on account of its multitude; and he commences with Ishmael, who was to be its head and origin. Although we shall afterwards see that he was a reprobate, yet an honorable name is granted to him, to mark the temporal benefit of which Ishmael became a partakers as being a son of Abram. For I thus explain the passage, God intended that a monument of the paternal kindness, with which he embraced the whole house of Abram, should endure to posterity. For although the covenant of eternal life did not belong to Ishmael; yet, that he might not be entirely without favor, God constituted him the father of a great and famous people. And thus we see that, with respect to this present life, the goodness of God extended itself to the seed of Abram according to the flesh. But if God intended the name of Ishmael (which signifies God will hear) to be a perpetual memorial of his temporal benefits; he will by no means bear with our ingratitude, if we do not celebrate his celestial and everlasting mercies, even unto death.

The Lord has heard thy affliction. We do not read that Hagar, in her difficulties, had recourse to prayer; and we are rather left to conjecture, from the words of Moses, that when she was stupefied by her sufferings, the angel came of his own accord. It is therefore to be observed, that there are two ways in which God looks down upon men, for the purpose of helping them; either when they, as suppliants, implore his aid; or when he, even unasked, succours them in their afflictions. He is indeed especially said to hearken to them who, by prayers, invoke him as their Deliverer. Yet, sometimes, when men lie mute, and because of their stupor, do not direct their wishes to him, he is said to listen to their miseries. That this latter mode of hearing was fulfilled towards Hagar, is probable, because God freely met her wandering through the desert. Moreover, because God frequently deprives unbelievers of his help, until they are worn away with slow disease, or else suffers them to be suddenly destroyed; let none of us give indulgence to our own sloth; but being admonished by the sense of our evils, let us seek him without delay. In the meantime, however, it is of no small avail to the confirmation of our faith, that our prayers will never be despised by the Lord, seeing that he anticipates even the slothful and the stupid, with his help; and if he is present to those who seek him not, much more will he be propitious to the pious desires of his own people.
