From H2616 (related to chesed), this adjective describes someone who is characterized by chesed (lovingkindness). It refers to a person who is pious, devout, and loyal to God's covenant. It is often translated as "godly," "saint," or "holy one."
A chasid is one who has received God's chesed and, in turn, lives a life of covenant loyalty and devotion to Him. The term is frequently used in the Psalms to describe the ideal worshipper of Yahweh, one who trusts in God and lives according to His ways. It speaks to the relational aspect of holinessโnot just ritual purity, but a life characterized by love and faithfulness to God. These are the people God promises to preserve and protect.
