Numbers 7:16

One kid of the goats for a sin offering.
] Though these offerings of the princes were by way of thanksgiving, and to express their joy and gladness at the erection of the tabernacle, its altars, and the service thereof; yet as this might not be without sin, which attends the best and purest performances of men, a sin offering was required, teaching us to look to Christ, who was made an offering for sin, for the taking away the sins of our holy things.
