"No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money." (NIV)

No one can serve two masters; for either he will hate the one and love the other, or he will stand by and be devoted to the one and despise and be against the other. You cannot serve God and mammon (deceitful riches, money, possessions, or whatever is trusted in). (AMP)

No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon. (KJV)
