Foot
The foot, as in Deuteronomy 33:3, signifies an inferior principle. To set the right foot on the sea and the left on the earth, as in Revelation 10:2, signifies that the Lord has the universal church under His intuition and dominion.

Isaiah 13:9-10
9
Behold, the day of Yahweh comes, cruel, with wrath and fierce anger; to make the land a desolation, and to destroy its sinners out of it.
10
For the stars of the sky and its constellations will not give their light. The sun will be darkened in its going forth, and the moon will not cause its light to shine.
