25 If you use stones to build my altar, use only natural, uncut stones. Do not shape the stones with a tool, for that would make the altar unfit for holy use.

Matthew Henry's Commentary on Exodus 20:25

Commentary on Exodus 20:22-26

(Read Exodus 20:22-26)

Moses having entered into the thick darkness, God there spake in his hearing all that follows from hence to the end of chap. 23, which is mostly an exposition of the ten commandments. The laws in these verses relate to God's worship. The Israelites are assured of God's gracious acceptance of their devotions. Under the gospel, men are encouraged to pray every where, and wherever God's people meet in his name to worship him, he will be in the midst of them; there he will come unto them, and will bless them.
