Yahweh’s Book recorded the origin of 7 – Day Weekly Cycle in Genesis 1:1-31; 2:1-3. Yahweh Created the Sun, Moon, and stars strictly after the end of 3^rd of the Week at 18 hours on Tuesday 23^rd February 4234 BCE, at 35°E Jerusalem (Genesis 1:13-19). Yahweh and Adam took rest on Sabbath Day (From 6 PM on Friday to 6 PM on Saturday on the Horizon). So those who deny the Sabbath are the seed of Serpent (Jeremiah 11:1-5; Matthews 25:41; Mark 2:27-28; Isaiah 56:1-7; Col. 2:16; Rom. 2:24-29; 3:31; 11:1-122; Gal. 2:14; 1:6-10; 3:26-29; 1 Cor. 16:21-22). This proof is enough for you.
