This threeness-in-oneness or oneness-in-manyness can be seen throughout Genesis chapter one. Thus in this one creation account — within God Triune — there are clear inferences anent the Father, Word and Spirit (Gen. 1:1-3 & 1:26). There are two parallel series of three days each — on which God Triune respectively made light, and lights; the atmosphere/sea, and their inhabitants; and the dry land, and its inhabitants (Gen. 1:3- 31).
On day one — He made light, evening, and morning (Gen. 1:3-5). On day two — He made the firmament, the waters below, and the waters above (Gen. 1:6-8). On day three — He made the grass, the herbs, and the trees (Gen. 1:9-13). On day four — He made the sun, the moon, and the stars; and for days, seasons, and years (Gen. 1:14-19). On day five — He made water-monsters, sea-creatures, and things with wings (Gen. 1:20-23).
