[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.
