He lied about his name (vv. 18-19). Did Isaac ask for identification because he was hard of hearing? Probably not (v. 22); it’s likely he was starting to get suspicious because he didn’t expect Esau to return so quickly from the hunt (v. 20). Furthermore, the voice he heard didn’t sound like the voice of Esau. That’s when Jacob told his first lie: He claimed to be Esau.
