Exodus 20:24-25

20:24 ‘You must make for me an altar made of earth, ¹  and you will sacrifice on it your burnt offerings and your peace offerings, ²  your sheep and your cattle. In every place ³  where I cause my name to be honored ⁴  I will come to you and I will bless you. 20:25 If you make me an altar of stone, you must not build it ⁵  of stones shaped with tools, ⁶  for if you use your tool on it you have defiled it. ⁷ 

[20:24]  ¹ sn The instructions here call for the altar to be made of natural things, not things manufactured or shaped by man. The altar was either to be made of clumps of earth or natural, unhewn rocks.

[20:24]  ² sn The “burnt offering” is the offering prescribed in Lev 1. Everything of this animal went up in smoke as a sweet aroma to God. It signified complete surrender by the worshiper who brought the animal, and complete acceptance by God, thereby making atonement. The “peace offering” is legislated in Lev 3 and 7. This was a communal meal offering to celebrate being at peace with God. It was made usually for thanksgiving, for payment of vows, or as a freewill offering.

[20:24]  ³ tn Gesenius lists this as one of the few places where the noun in construct seems to be indefinite in spite of the fact that the genitive has the article. He says בְּכָל־הַמָּקוֹם (bÿkhol-hammaqom) means “in all the place, sc. of the sanctuary, and is a dogmatic correction of “in every place” (כָּל־מָקוֹם, kol-maqom). See GKC 412 §127.e.

[20:24]  ⁴ tn The verb is זָכַר (zakhar, “to remember”), but in the Hiphil especially it can mean more than remember or cause to remember (remind) – it has the sense of praise or honor. B. S. Childs says it has a denominative meaning, “to proclaim” (Exodus [OTL], 447). The point of the verse is that God will give Israel reason for praising and honoring him, and in every place that occurs he will make his presence known by blessing them.

[20:25]  ⁵ tn Heb “them” referring to the stones.

[20:25]  ⁶ tn Heb “of hewn stones.” Gesenius classifies this as an adverbial accusative – “you shall not build them (the stones of the altar) as hewn stones.” The remoter accusative is in apposition to the nearer (GKC 372 §117.kk).

[20:25]  ⁷ tn The verb is a preterite with vav (ו) consecutive. It forms the apodosis in a conditional clause: “if you lift up your tool on it…you have defiled it.”
