'Work of the Lord' in the Bible

Then Jesus said to them, "Did you never read in the Scriptures: 'That stone which the builders threw away has become the cornerstone; this is the work of the Lord and seems wonderful to us!'

This is the work of the Lord, and seems wonderful to us'?"

Remember me to Tryphaena and Tryphosa, who continued to toil in the work of the Lord. Remember me to my dear friend Persis, who toiled so hard in the work of the Lord.

So, my dear brothers, continue to be firm, incapable of being moved, always letting the cup run over in the work of the Lord, because you know that your labor in the service of the Lord is never thrown away.

If Timothy gets there, see that he is at ease among you, for he is devotedly doing the work of the Lord, just as I am.
