Genesis 1:21-22

1:21 God created the great sea creatures ¹  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. 1:22 God blessed them ²  and said, “Be fruitful and multiply and fill the water in the seas, and let the birds multiply on the earth.” ³ 

Numbers 1:46

1:46 And all those numbered totaled 603,550.

Numbers 26:34

26:34 These were the families of Manasseh; those numbered of them were 52,700. ⁴ 

Numbers 26:37

26:37 These were the families of the Ephraimites, according to those numbered of them, 32,500. ⁵  These were the descendants of Joseph by their families.

[1:21]  ¹ 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.

[1:22]  ² tn While the translation “blessed” has been retained here for the sake of simplicity, it would be most helpful to paraphrase it as “God endowed them with fruitfulness” or something similar, for here it refers to God’s giving the animals the capacity to reproduce. The expression “blessed” needs clarification in its different contexts, for it is one of the unifying themes of the Book of Genesis. The divine blessing occurs after works of creation and is intended to continue that work – the word of blessing guarantees success. The word means “to enrich; to endow,” and the most visible evidence of that enrichment is productivity or fruitfulness. See C. Westermann, Blessing in the Bible and the Life of the Church (OBT).

[1:22]  ³ sn The instruction God gives to creation is properly a fuller expression of the statement just made (“God blessed them”), that he enriched them with the ability to reproduce. It is not saying that these were rational creatures who heard and obeyed the word; rather, it stresses that fruitfulness in the animal world is a result of the divine decree and not of some pagan cultic ritual for fruitfulness. The repeated emphasis of “be fruitful – multiply – fill” adds to this abundance God has given to life. The meaning is underscored by the similar sounds: בָּרָךְ (barakh) with בָּרָא (bara’), and פָּרָה (parah) with רָבָה (ravah).

[26:34]  ⁴ sn The Manassehites increased from 32,200 to 52,700.

[26:37]  ⁵ sn This is a significant reduction from the first count of 40,500.
