56 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).
57 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).
