Jacob Builds an Altar and Israel Accepts God's Kingship

Midrash Tanchuma Buber, Vayishlach 10:6

And afterward he [Jacob] took His [God's] kingship upon himself, as it is said (Genesis 33:20): "And he set up there an altar, etc." And they [Israel] too took His kingship upon themselves, as it is said (Exodus 20:2): "I am the LORD your God." What did they say? They all answered with one mouth and said (Exodus 24:7): "All that the LORD has spoken we will do and we will obey." This is the meaning of (Job 22:28): "You shall decree a thing, and it shall be established for you."
