And thou shall take the atonement money of the children of Israel,.... The half shekel, the ransom of their souls: and shall appoint it for the service of the tabernacle of the congregation; for the building of the tabernacle, for the repairs of it, and for the sacrifices offered in it; particularly we find that this first collection this way was appropriated to the silver sockets of the sanctuary, and the vail, for the silver hooks, and for the pillars, Exo 38:27, that it may be a memorial unto the children of Israel before the Lord, to make an atonement for your souls; to put them in mind that they were sinners, that their lives were forfeited, that a ransom price was given and accepted of God, that hereby atonement, in a typical sense, was made for them; and this was before the Lord, as a token of their gratitude to him, and of their acknowledgment of the favour.
