'Contend' in the Bible

Wherefore would ye contend with me? Ye all have transgressed against me, saith Jehovah.

If thou hast run with footmen, and they have wearied thee, how wilt thou then contend with horses? And if in a land of peace thou thinkest thyself in security, how wilt thou then do in the swelling of the Jordan?

Jehovah, give heed to me, and listen to the voice of those that contend with me.
