'Worship' in the Bible

And he said, No; but I have come as captain of the armies of the Lord. Then Joshua, falling down with his face to the earth in worship, said, What has my lord to say to his servant?

Have nothing to do with these nations who still are living among you; let not their gods be named by you or used in your oaths; do not be their servants or give them worship:

If the agreement of the Lord your God, which was given to you by his orders, is broken, and you become the servants of other gods and give them worship, then the wrath of the Lord will be burning against you, and you will quickly be cut off from the good land which he has given you.
