'Omen' in the Bible

“For there is no omen against Jacob,Nor is there any divination against Israel;At the proper time it shall be said to JacobAnd to Israel, what God has done!

Now the men took this as an omen, and quickly catching his word said, “Your brother Ben-hadad.” Then he said, “Go, bring him.” Then Ben-hadad came out to him, and he took him up into the chariot.
