'Labour' in the Bible

and he who is planting and he who is watering are one, and each his own reward shall receive, according to his own labour,

and labour, working with our own hands; being reviled, we bless; being persecuted, we suffer;

and by the grace of God I am what I am, and His grace that is towards me came not in vain, but more abundantly than they all did I labour, yet not I, but the grace of God that is with me;

so that, my brethren beloved, become ye stedfast, unmovable, abounding in the work of the Lord at all times, knowing that your labour is not vain in the Lord.
