In Buddhism, a sotāpanna is said to not take an eighth rebirth, while in monotheistic traditions (Genesis), it is said that God created the world in seven days, of which the last day was the day for resting (The Sabbath):
“Thus the heavens and the earth, and all the host of them, were finished. And on the seventh day God ended His work which He had done, and He rested on the seventh day from all His work which He had done. Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made” (Genesis 2:1-3).
Do you think there is a connection between the two? or is it completely accidental?"Those who realized the Noble Truths well taught by him who is profound in wisdom (the Buddha), even though they may be exceedingly heedless, they will not take an eighth existence (in the realm of sense spheres). This precious jewel is the Sangha. By this (asseveration of the) truth may there be happiness.
