Salem

Salem was the first recorded name of Jerusalem revealed in the Scriptures. Jeru means city and the word "Salem" comes from the Hebrew 'Shalom" and means "Peace" but it means much more than peace, shalom has a connotation of wholeness, contentment, blessing, prosperity, and lack of aggression. Genesis 14 reveals that Melchizedek was the king of Salem when Abraham met him and paid him tithes from his spoils of the war against the kings of the east. David said, " In Salem is the tabernacle and his dwelling place in Zion " (Ps. 76:2).
