Charles Spurgeon Commentary Hebrews 7:1-2

"For this Melchizedek, king of Salem, priest of God Most High, who met Abraham returning from the slaughter of the kings and blessed him, to whom also Abraham divided a tenth part of all (being first, by interpretation, King of righteousness, and then also King of Salem, which is King of peace;" — Hebrews 7:1-2 (ASV)

His very names being instructive, Righteousness first, and Peace afterwards, as it is with our divine Lord, who has brought in everlasting righteousness, and speaks peace to guilty men.
