“And Dauid sayd to Abishai, Destroy him not: for who can stretch forth his hand against the Lords Anointed, and be guiltlesse?”
1611 King James Version (KJV)
26:9 Destroy him not, &c. - Though Saul be a tyrant, yet he is our Lord and king; and I, though designed king, as yet am his subject; and therefore cannot kill him without sin, nor will I consent that thou shouldst do it.
