'Combating' in the Bible

Whereunto also I toil, combating according to his working, which works in me in power.

These rules have indeed an appearance of wisdom where self-imposed worship exists, and an affectation of humility and an ascetic severity. But not one of them is of any value in combating the indulgence of our lower natures.

Epaphras, who is one of you, the bondman of Christ Jesus, salutes you, always combating earnestly for you in prayers, to the end that ye may stand perfect and complete in all the will of God.
