The Holy One, blessed be He, created seven seas, and of them all He chose the Sea of Kinnereth only, and gave it as an inheritance to the tribe of Naphtali, as it is said, "O Naphtali, satisfied with favour, and full with the blessing of the Lord: possess thou the sea and the south" (Deut. 33:23). What is the "blessing of the Lord"? (It means) that He blessed him and gave him as an inheritance the sea and the south, as it is said, "Possess thou the sea and the south" (ibid.).
The Holy One, blessed be He, created seven æons, ∥ and of them all He chose the seventh æon only; the six æons are for the going in and coming out (of God's creatures) for war and peace. The seventh æon is entirely Sabbath and rest in the life everlasting. Seven lamps were made for the sanctuary, and the lamp of Sabbath was illuminating opposite the other six (lamps), as it is said, "In front of the lamp-stand the seven lamps shall give light" (Num. 8:2). The Holy One, blessed be He, created seven days, and of them all He chose the seventh day only, as it is said, "And God blessed the seventh day, and hallowed it" (Gen. 2:3).
