'Serve the Lord' in the Bible
“Now, therefore, fear the Lord and serve Him in sincerity and truth; and put away the gods which your fathers served beyond the River and in Egypt, and serve the Lord.
If it is disagreeable in your sight to serve the Lord, choose for yourselves today whom you will serve: whether the gods which your fathers served which were beyond the River, or the gods of the Amorites in whose land you are living; but as for me and my house, we will serve the Lord.”
The Lord drove out from before us all the peoples, even the Amorites who lived in the land. We also will serve the Lord, for He is our God.”
Then Joshua said to the people, “You will not be able to serve the Lord, for He is a holy God. He is a jealous God; He will not forgive your transgression or your sins.
The people said to Joshua, “We will serve the Lord our God and we will obey His voice.”
