'Assignment' in the Bible

But we will not boast {beyond limits}, but according to the measure of the assignment that God has assigned to us as a measure to reach even as far as you.

not boasting {beyond limits} in the labors of others, but having hope [that as] your faith is growing to be enlarged greatly by you according to our assignment,

Are they not all spirits engaged in special service, sent on assignment for the sake of those who are going to inherit salvation?
