2:20 wisdom and might are his. In Christ “are hid all the treasures of wisdom and knowledge” (Colossians 2:3), and to Christ has been given “all power…in heaven and in earth” (Matthew 28:18).

2:21 times and seasons. God established the sun, moon, and stars with their motions, to serve for the measurement of time and the establishment of seasons (Genesis 1:14). The great Flood may well have resulted in changes in these. For example, the year may have been 360 days long in antediluvian times (Genesis 7:11,24; 8:4,14), and the distinctiveness of the seasons was probably accentuated by the upheavals of the Flood.

2:21 understanding. See on Daniel 1:17.

2:22 darkness. God “created darkness,” but “God is light,” He “dwelleth in the light,” and needed only to divide “the light from the darkness” when He created heaven and earth (Isaiah 45:7; I John 1:5; I Timothy 6:16; Genesis 1:4).
