Genesis 1:14-15
Context1:14 God said, “Let there be lights 4 in the expanse 5 of the sky to separate the day from the night, and let them be signs 6 to indicate seasons and days and years, 1:15 and let them serve as lights in the expanse of the sky to give light on the earth.” It was so.
1 tn The prefixed verb form with the vav (ו) consecutive introduces the narrative sequence. Ten times in the chapter the decree of God in creation will be so expressed. For the power of the divine word in creation, see Ps 33:9, John 1:1-3, 1 Cor 8:6, and Col 1:16.
sn God said. By speaking, God brings the world into existence. The efficacious nature of the word of the
2 tn “Let there be” is the short jussive form of the verb “to be”; the following expression “and there was” is the short preterite form of the same verb. As such, יְהִי (yÿhi) and וַיְהִי (vayÿhi) form a profound wordplay to express both the calling into existence and the complete fulfillment of the divine word.
3 sn Light. The Hebrew word simply means “light,” but it is used often in scripture to convey the ideas of salvation, joy, knowledge, righteousness, and life. In this context one cannot ignore those connotations, for it is the antithesis of the darkness. The first thing God does is correct the darkness; without the light there is only chaos.
4 sn Let there be lights. Light itself was created before the light-bearers. The order would not seem strange to the ancient Hebrew mind that did not automatically link daylight with the sun (note that dawn and dusk appear to have light without the sun).
5 tn The language describing the cosmos, which reflects a prescientific view of the world, must be interpreted as phenomenal, describing what appears to be the case. The sun and the moon are not in the sky (below the clouds), but from the viewpoint of a person standing on the earth, they appear that way. Even today we use similar phenomenological expressions, such as “the sun is rising” or “the stars in the sky.”
6 tn The text has “for signs and for seasons and for days and years.” It seems likely from the meanings of the words involved that “signs” is the main idea, followed by two categories, “seasons” and “days and years.” This is the simplest explanation, and one that matches vv. 11-13. It could even be rendered “signs for the fixed seasons, that is [explicative vav (ו)] days and years.”
sn Let them be for signs. The point is that the sun and the moon were important to fix the days for the seasonal celebrations for the worshiping community.
