'Loyal' in the Bible

"No one can serve two masters, because either he will hate one and love the other, or be loyal to one and despise the other. You cannot serve God and riches!"

"No servant can serve two masters, because either he will hate one and love the other, or be loyal to one and despise the other. You cannot serve both God and wealth!"

It will not be like the covenant that I made with their ancestors at the time when I took them by the hand and brought them out of the land of Egypt. Because they did not remain loyal to my covenant, I ignored them, declares the Lord.
