Kejadian 1:20-21

1:20 God said, “Let the water swarm with swarms ¹  of living creatures and let birds fly ²  above the earth across the expanse of the sky.” 1:21 God created the great sea creatures ³  and every living and moving thing with which the water swarmed, according to their kinds, and every winged bird according to its kind. God saw that it was good.

[1:20]  ¹ tn The Hebrew text again uses a cognate construction (“swarm with swarms”) to emphasize the abundant fertility. The idea of the verb is one of swift movement back and forth, literally swarming. This verb is used in Exod 1:7 to describe the rapid growth of the Israelite population in bondage.

[1:20]  ² tn The Hebrew text uses the Polel form of the verb instead of the simple Qal; it stresses a swarming flight again to underscore the abundant fruitfulness.

[1:21]  ³ tn For the first time in the narrative proper the verb “create” (בָּרָא, bara’) appears. (It is used in the summary statement of v. 1.) The author wishes to underscore that these creatures – even the great ones – are part of God’s perfect creation. The Hebrew term תַנִּינִם (tanninim) is used for snakes (Exod 7:9), crocodiles (Ezek 29:3), or other powerful animals (Jer 51:34). In Isa 27:1 the word is used to describe a mythological sea creature that symbolizes God’s enemies.
