'Labour' in the Bible

Wherefore we labour, that, whether present or absent, we may be accepted of him.

We do not exceed our due limits, and take credit for other men's labours; but we entertain the hope that, as your faith grows, we shall gain promotion among you--still keeping within our own sphere--promotion to a larger field of labour,

in labour and toil, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness.
