King James Version (KJV)
And it came to pass, when he began to reign, as soon as he sat on his throne, {that} he slew all the house of Baasha: he left him not one that pisseth against a wall, neither of his kinsfolks, nor of his friends. {neither...: or, both his kinsmen and his friends}
Modern English
When he began to reign, as soon as he sat on his throne, he attacked all the house of Baasha. He didn’t leave him a single one who urinates on a wall among his relatives or his friends.
Hebrew
