'Terrible' in the Bible

Moreover, after they had cast a golden calf for themselves, they said, "This is your god who brought you out of Egypt!" and committed terrible blasphemies.

"Then they disobeyed, rebelled against you, and threw your Law behind their backs. They murdered your prophets who had admonished the people to return to you, committing terrible blasphemies.

Should we listen to you and do all of this terrible evil by transgressing against our God to marry foreign wives?"
