35:28 and spices and olive oil for the light, for the anointing oil, and for the fragrant incense.

[29:4]  ¹ tn Here too the verb is Hiphil (now imperfect) meaning “bring near” the altar. The choice of this verb indicates that they were not merely being brought near, but that they were being formally presented to Yahweh as the offerings were.

[29:4]  ² sn This is the washing referred to in Lev 8:6. This is a complete washing, not just of the hands and feet that would follow in the course of service. It had to serve as a symbolic ritual cleansing or purifying as the initial stage in the consecration. The imagery of washing will be used in the NT for regeneration (Titus 3:5).
