'Ground' in the Bible

It is no good thing--this which you make the ground of your boasting. Do you not know that a little yeast corrupts the whole of the dough?

This is my defense to those who would put me on trial and interrogate me [concerning my authority as an apostle]:

But I have used none of these privileges, nor am I writing this [to suggest] that any such provision be made for me now. For it would be better for me to die than to have anyone deprive me of my boast [in this matter of financial support].

Nevertheless, God was not well-pleased with most of them, for they were scattered along the ground in the wilderness [because their lack of self-control led to disobedience which led to death].

But now I mean his conscience, not your own. "Why, on what ground," you may object, "is the question of my liberty of action to be decided by a conscience not my own?

His secret, inner heart will become known, and so he will bow down to the ground and worship God, declaring, "God is truly among you!"
