'Discharge' in the Bible

In discharge of the task which God graciously entrusted to me, I--like a competent master-builder--have laid a foundation, and others are building upon it. But let every one be careful how and what he builds.

And tell Archippus to discharge carefully the duties devolving upon him as a servant of the Lord.

But as for you, you must exercise habitual self-control, and not live a self-indulgent life, but do the duty of an evangelist and fully discharge the obligations of your office.
