Genesis 16:4

We have here the immediate bad consequences of Abram's unhappy marriage to Hagar. A great deal of mischief it made quickly. When we do not well both sin and trouble lie at the door; and 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 story. I. Sarai is despised, and thereby provoked and put into a passion, Gen 16:4. Hagar no sooner perceives herself with child by her master than she looks scornfully upon her mistress, upbraids her perhaps with her barrenness, insults over her, to make her to fret (as Sa1 1:6), and boasts of the prospect she had of bringing an heir to Abram, to that good land, and to the promise. Now she thinks herself a better woman than Sarai, more favoured by Heaven, and likely to be better beloved by Abram; and therefore she will not submit as she has done. Note, 1. Mean and servile spirits, when favoured and advanced either by God or man, are apt to grow haughty and insolent, and to forget their place and origin. See Pro 29:21; Pro 30:21-23. It is a hard thing to bear honour aright. 2. We justly suffer by those whom we have sinfully indulged, and it is a righteous thing with God to make those instruments of our trouble whom we have made instruments of our sin, and to ensnare us in our own evil counsels: this stone will return upon him that rolleth it. II. Abram is clamoured upon, and cannot be easy while Sarai is out of humour; she upbraids him vehemently, and very unjustly charges him with the injury (Gen 16:5): My wrong be upon thee, with a most unreasonable jealousy suspecting that he countenanced Hagar's insolence; and, as one not willing to hear what Abram had to say for the rectifying of the mistake and the clearing of himself, she rashly appeals to God in the case: The Lord j…

16:4-6 Perhaps Hagar expected to become the favored wife instead of Sarai (cp. Prov 30:21-23).
