'Ground' in the Bible

Then Ezra blessed Yahweh the great God, and all of the people answered, "Amen! Amen!" while lifting their hands. Then they bowed down and worshiped Yahweh [with their] noses to the ground.

And you divided the sea before them, and they passed through the sea on dry ground, but their pursuers you threw into the depths like a stone into mighty waters.
