הלכה על יונה 2:1

Now the darkness proceeded the light, as it is written (Genesis 1:2). The great movement (diurnal movement) includes the time of darkness and light, and that is called “yom” (day), that is, a complete day of twenty-four hours.¹⁸ Thus “day” includes a period of darkness and a period of light, in that order. This does not conflict with the fact that Scripture first mentioned “God called the light ‘day’” (Genesis 1:5) before the night, for this is common with the Hebrew language, namely, when someone mentions two things he should begin with the latter.¹⁹ Verses 3 and 4 refer to the light, therefore verse 5 begins by calling the light “day.” For example, “I gave Jacob and Esau to Isaac, and I gave to Esau…” (Joshua 24:4). In the same way, “Your’s is the day also the night” (Psalms 74:16), and he mentions the minor luminary (the moon) that governs the night before the greater luminary (the sun), although the latter is more important than the former. Also, do not be perplexed when Scripture says “He formed the light and created darkness” (Isaiah 40:12). Scripture puts the light first because it has advantages over darkness, even though darkness came before the light. Similarly, in the verse “His sons Isaac and Ishmael” (Genesis 25:9).²⁰ Isaac is mentioned first, even though he was the younger son. Also, “There they buried Abraham and Sarah his wife” (ibid. 49:31), although he buried her.²¹ Abraham is mentioned first although Sarah was buried first.
