Talmud Bavli Yoma on the Foundation Stone in Zion

"Rabbi Eliezer says: The world was created from its center, as it says: 'When dirt was poured to a single bedrock and clumps stuck around it' (Job 38:38). Rabbi Yehoshua says: The world was created from its four sides, as it says: 'For he says to the snow: Become the earth! From showers and rain, from showers and his mighty rains' (Job 37:6). Rabbi Yitzchak said: The Holy One, Blessed be He, threw a stone into the sea and from that stone the earth was founded, as it says: 'Do you know into what its bases are sunken, or who cast down its cornerstone?' (Job 38:6). But the sages say: The world was created from Zion, as it says: 'A song by Asaph, O Almighty God, YHVH spoke and called forth the earth' (Psalms 50:1). And it says in the next verse, 'Out of Zion, consummation of beauty'. From Zion, the beauty of the world was consummated."
