Leeser(i)
20 In his days Edom revolted from under the power of Judah, and they appointed a king over themselves.
21 And Joram went over to Za’ir, and all the chariots were with him; and he rose up by night, and smote the Edomites who compassed him about, and the captains of the chariots: and the people fled unto their tents.
22 Yet Edom revolted from under the power of Judah even until this day; then did Libnah revolt at the same time.
