¹³Thou shalt fear the Lord thy God, and serve him, and shalt swear by his name.¹⁴Ye shall not go after other gods, of the gods of the people which are round about you; ¹⁵ (For the Lord thy God is a jealous God among you) lest the anger of the Lord thy God be kindled against thee, and destroy thee from off the face of the earth.

A dramatic warning from the Old Testament! Fear God and do not pursue the gods (idols) of the world. If you do, he will wipe you off the face of the earth!
