Leviticus 1:4

He shall put his hand Both his hands; Leviticus 8:14; Leviticus 8:18; Leviticus 16:21; whereby he signified, 1st. That he willingly gave it to the Lord; 2d, That he judged himself worthy of that death which it suffered in his stead; and that he laid his sins upon it with an eye to him upon whom God would lay the iniquity of us all, (Isaiah 53:6,) and that together with it he did freely offer up himself to God. To make atonement Sacramentally; as directing his faith and thoughts to that true propitiatory sacrifice which in time was to be offered up for him. And although burnt-offerings were commonly offered by way of thanksgiving, yet they were sometimes offered by way of atonement for sin, that is, for sins in general, as appears from Job 1:5; but for particular sins there were special sacrifices.
