And he went in unto Hagar, and she conceived: and when she saw that she had conceived, her mistress was {c} despised in her eyes.

(c) This punishment declares what they gain if they attempt any thing against the word of God.

Wesley's Notes

16:4 We have here the ill consequences of Abram's marriage to Hagar: a deal of mischief it made presently. Hagar no sooner perceives herself with child, but she looks scornfully upon her mistress; upbraids her perhaps with her barrenness, and insults over her. Sarai falls upon Abram, and very unjustly charges him with the injury, suspecting that he countenanced Hagar's insolence: and as one not willing to hear what Abram had to say she rashly appeals to God. The Lord judge between me and thee, as if Abram had refused to right her. When passion is upon the throne, reason is out of doors, and is neither heard nor spoken. Those are not always in the right that are most forward in appealing to God. Rash and bold imprecations are commonly evidences of guilt and a bad cause.

Matthew Henry's Concise Commentary

16:4-6 Abram's unhappy marriage to Hagar very soon made a great deal of mischief. We may thank ourselves for the guilt and grief that follow us, when we go out of the way of our duty. See it in this case, Passionate people often quarrel with others, for things of which they themselves must bear the blame. Sarai had given her maid to Abram, yet she cries out, My wrong be upon thee. That is never said wisely, which pride and anger put into our mouths. Those are not always in the right, who are most loud and forward in appealing to God: such rash and bold imprecations commonly speak guilt and a bad cause. Hagar forgot that she herself had first given the provocation, by despising her mistress. Those that suffer for their faults, ought to bear it patiently, 1Pe 2:20.
