Kejadian 6:18

6:18 but I will confirm ¹  my covenant with you. You will enter ²  the ark – you, your sons, your wife, and your sons’ wives with you.

Kejadian 21:10

21:10 So she said to Abraham, “Banish ³  that slave woman and her son, for the son of that slave woman will not be an heir along with my son Isaac!”

[6:18]  ¹ tn The Hebrew verb וַהֲקִמֹתִי (vahaqimoti) is the Hiphil perfect with a vav (ו) consecutive (picking up the future sense from the participles) from קוּם (qum, “to rise up”). This may refer to the confirmation or fulfillment of an earlier promise, but it is more likely that it anticipates the unconditional promise made to humankind following the flood (see Gen 9:9, 11, 17).

[6:18]  ² tn The perfect verb form with vav (ו) consecutive is best understood as specific future, continuing God’s description of what will happen (see vv. 17-18a).

[21:10]  ³ tn Heb “drive out.” The language may seem severe, but Sarah’s maternal instincts sensed a real danger in that Ishmael was not treating Isaac with the proper respect.
