Exodus 20:25-26

20:25 If you make me an altar of stone, you must not build it ¹  of stones shaped with tools, ²  for if you use your tool on it you have defiled it. ³  20:26 And you must not go up by steps to my altar, so that your nakedness is not exposed.’ ⁴ 

[20:25]  ¹ tn Heb “them” referring to the stones.

[20:25]  ² 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]  ³ 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.”

[20:26]  ⁴ tn Heb “uncovered” (so ASV, NAB).
