Why did Ehud use the word "God" here?

Judges 3:20 (ESV)

20 And Ehud came to him as he was sitting alone in his cool roof chamber. And Ehud said, “I have a message from God for you.” And he arose from his seat.

Eglon would not have known or respected Yahweh, Lord, but would have respected the unspecified God.
