Keluaran 27:6-7

27:6 You are to make poles for the altar, poles of acacia wood, and you are to overlay them with bronze. 27:7 The poles are to be put ¹  into the rings so that the poles will be on two sides of the altar when carrying it. ² 

[27:7]  ¹ tn The verb is a Hophal perfect with vav consecutive: וְהוּבָא (vÿhuva’, “and it will be brought”). The particle אֶת (’et) here introduces the subject of the passive verb (see a similar use in 21:28, “and its flesh will not be eaten”).

[27:7]  ² tn The construction is the infinitive construct with bet (ב) preposition: “in carrying it.” Here the meaning must be that the poles are not left in the rings, but only put into the rings when they carried it.
