בְּרֵאשִׁ֖ית בָּרָ֣א אֱלֹהִ֑ים אֵ֥ת הַשָּׁמַ֖יִם וְאֵ֥ת הָאָֽרֶץ׃
태초에 하나님이 천지를 창조하시니라
Rabbeinu Yonah
With ten utterances the world was created. And what is learned: "And He said" is written nine times from "In the beginning" (Genesis 1:1) to "And completed" (Genesis 2:1). And "In the beginning" is also an utterance, as it is stated (Psalms 33:6), "By the word of the Lord the heavens were made" - as it is impossible that the heavens and the earth were created without an utterance.
Ibn Ezra
בליל In the night of.1A. V., In the night. ליל is in the construct state. It is an elliptical expression for in the night of such and such a day of the week.2An ellipsis, as supposed here by I. E. would be very unnatural; the qualified word may easily be omitted, but not the qualifying; we omit, e.g the house, but not the qualifying genitive. If לֵיל could only be the construct state, the whole sentence, שדד ער מואב, should be taken as the genitive; comp. Gen. 1:1, Hos. 1:1. See I. E. on Is. 21:11, and Moznaim, On the elliptical phrases in the Bible.

Elohim refers only to Judge. . . Although it says: “In the beginning Elohim created” (Bereishis 1:1), and: “Elohim said to Noach” (ibid. 8:15), and: “Elohim called to him from the midst of the thorn-bush” (Shemos 3:4), see Re”m here and in 6:2 [for an explanation of these verses].
