'Serve the Lord' in the Bible

And if it seem evil unto you to serve the LORD, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the LORD.

And the LORD drave out from before us all the people, even the Amorites which dwelt in the land: therefore will we also serve the LORD; for he is our God.

And Joshua said unto the people, Ye cannot serve the LORD: for he is an holy God; he is a jealous God; he will not forgive your transgressions nor your sins.

And the people said unto Joshua, Nay; but we will serve the LORD.
