The ancient people believed that knowing the true name of a God gave humans power over it. When God did reveal his name to them he gave them YHWH. Because vowels were not written it's difficult for us to know exactly how it was said. But common translation pronounces it as Yahweh and then it's translated again in to English as Jehovah.
HOWEVER... The roughtly translated Yehweh in the ancient Canaanite language actually means "I am what I am" So in essance he was not giving them his name, he was actively refusing to allow them to believe they had any power.
SO, what it boils down to is that Jehovah or Yehweh are the names we associate with Abrahams god, but is not his actual name. However it is the name that HE gave to his people to use. So that would have to mean that it's what he expects them to use.
