Yahweh

Yahweh is the personal name of the god of the Israelites in the Hebrew Bible. The name “Yahweh” is a modern scholarly convention, as rendered in Roman letters it is simply “YHWH.” There is no conclusive meaning for the name among scholars, but most likely it’s something along the lines of “He Brings Into Existence Whatever Exists.”

The Hebrew Bible describes Yahweh as the one true God who delivered Israel from Egypt and, through Moses, issued the Ten Commandments. Yahweh revealed himself as a jealous god to the Israelites, who would not suffer any rivals, forbidding the worship of idols or gods of other nations. It was to be a strictly monogamous human-deity relationship. Many of the religions in the surrounding area around roughly this time (mid-2nd millennia BCE) were polytheistic, but another major with Yahweh was his requirement of real faith. All worshippers were expected to believe in and recognize their respective gods, the Israelites were told “you shall love Yahweh your God with all your heart, and with all your soul, and with all your might.” 

Other gods demanded sacrifice and recognition, but you never would’ve been asked by, say, a Greek priest: “Have you accepted Lord Poseidon into your heart?”
