1:12. These verses have traditionally been understood as referring to the actual beginning of matter, a Creation out of nothing and therefore part of day one. But the vocabulary and grammar of this section require a closer look. The motifs and the structure of the Creation account are introduced in the first two verses. That the universe is Gods creative work is perfectly expressed by the statement God created the heavens and the earth. The word bārā (created) may express creation out of nothing, but it certainly cannot be limited to that (cf. 2:7). Rather, it stresses that what was formed was new and perfect. The word is used throughout the Bible only with God as its subject.But 1:2 describes a chaos: there was waste and void, and darkness was over the surface of the deep. The clauses in verse 2 are apparently circumstantial to verse 3, telling the worlds condition when God began to renovate it. It was a chaos of wasteness, emptiness, and darkness. Such conditions would not result from Gods creative work (bārā); rather, in the Bible they are symptomatic of sin and are coordinate with judgment.
Moreover, Gods Creation by decree begins in verse 3, and the elements found in verse 2 are corrected in Creation, beginning with light to dispel the darkness. The expression formless and empty (ṯōhû wāḇōhû) seems also to provide an outline for chapter 1, which describes Gods bringing shape and then fullness to the formless and empty earth.
Some have seen a middle stage of Creation here, that is, an unfinished work of Creation (v. 2) that was later developed (vv. 325) into the present form. But this cannot be sustained by the syntax or the vocabulary.
Others have seen a gap between the first two verses, allowing for the fall of Satan and entrance of sin into the world that caused the chaos.
It is more likely that verse 1 refers to a relative beginning rather than the absolute beginning (Merrill F. Unger, Ungers Commentary on the Old Testament. 2 vols. Chicago: Moody Press, 1981, 1:5). The chapter would then be accounting for the Creation of the universe as man knows it, not the beginning of everything, and verses 12 would provide the introduction to it. The fall of Satan and entrance of sin into Gods original Creation would precede this.
