19:2 {a} This [is] the ordinance of the law which the LORD hath commanded, saying, Speak unto the children of Israel, that they bring thee a red heifer without spot, wherein [is] no blemish, [and] upon which never came yoke:
(a) According to this law and ceremony you shall sacrifice the red cow.
19:2 Red - A fit colour to shadow forth the bloody nature of sin, and the blood of Christ, from which this water and all other rites had their purifying virtue. No blemish - A fit type of Christ. Upon which never came yoke - Whereby may be signified, either that Christ in himself was free from all the yoke or obligation of God's command, till for our sakes he put himself under the law; or that Christ was not forced to undertake our burden and cross, but did voluntarily chuse it. He was bound and held with no other cords but those of his own love.
19:1-10 The heifer was to be wholly burned. This typified the painful sufferings of our Lord Jesus, both in soul and body, as a sacrifice made by fire, to satisfy God's justice for man's sin. These ashes are said to be laid up as a purification for sin, because, though they were only to purify from ceremonial uncleanness, yet they were a type of that purification for sin which our Lord Jesus made by his death. The blood of Christ is laid up for us in the word and sacraments, as a fountain of merit, to which by faith we may have constant recourse, for cleansing our consciences.
