“To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace;”
King James Version (KJV)
7:2 Being first - According to the meaning of his own name. King of righteousness, then - According to the name of his city. King of peace - So in him, as in Christ, righteousness and peace were joined. And so they are in all that believe in him.
Heb 7:2 To whom also Abraham gave a tenth part of all. Tithes were paid to him as priest of the Most High. King of righteousness. Such is the meaning of Melchizedek. The word may not be the name, but a title. King of Salem. This means "King of Peace". It will be observed that the payment of tithes for religious purposes is at least 400 years older than the Jewish law. See also Ge 28:22.
