'Terrible' in the Bible

“But cursed is the swindler who has a male in his flock and vows [to offer] it, but sacrifices to the Lord a blemished or diseased thing! For I am a great King,” says the Lord of hosts, “and My name is to be [reverently and greatly] feared among the nations.”

“Behold, I am going to send you Elijah the prophet before the coming of the great and terrible day of the Lord.
