'Condition' in the Bible

Only on this condition will we consent unto you: if ye will be as we are, that every male of you be circumcised;

Only on this condition will the men consent unto us to dwell with us, to become one people, if every male among us be circumcised, as they are circumcised.

And Nahash the Ammonite said unto them, On this condition will I make it with you, that all your right eyes be put out; and I will lay it for a reproach upon all Israel.
