Deuteronomy 27:6 Meaning and Commentary

Deuteronomy 27:6

Thou shall build the altar of the Lord thy God of whole
stones
And of such Joshua did build it, ( Joshua 8:31 ) ;

and thou shalt offer burnt offerings thereon unto the Lord thy God;
and very likely sin offerings too; for these frequently went together, the one to make atonement for sin, and the other as a gift, and by way of thankfulness for the acceptance of the former; and both typical of Christ, the true sacrifice, and the antitype of all the legal sacrifices.
