Context37:25 He made the incense altar of acacia wood. Its length was a foot and a half and its width a foot and a half – a square – and its height was three feet. Its horns were of one piece with it. 7
1 tn The form is an infinitive construct with the temporal preposition bet (ב), and a suffixed subjective genitive: “in their going in,” or, whenever they enter.
2 tn “Water” is an adverbial accusative of means, and so is translated “with water.” Gesenius classifies this with verbs of “covering with something.” But he prefers to emend the text with a preposition (see GKC 369 §117.y, n. 1).
3 tn The verb is a Qal imperfect with a nuance of final imperfect. The purpose/result clause here is indicated only with the conjunction: “and they do not die.” But clearly from the context this is the intended result of their washing – it is in order that they not die.
4 tn Here, too, the infinitive is used in a temporal clause construction. The verb נָגַשׁ (nagash) is the common verb used for drawing near to the altar to make offerings – the official duties of the priest.
5 tn The text uses two infinitives construct: “to minister to burn incense”; the first is the general term and expresses the purpose of the drawing near, and the second infinitive is epexegetical, explaining the first infinitive.
6 tn The translation “as an offering made by fire” is a standard rendering of the one word in the text that appears to refer to “fire.” Milgrom and others contend that it simply means a “gift” (Leviticus 1-16, 161).
7 tn Heb “from it were its horns,” meaning that they were made from the same piece.
