Scripture Text
Thesis
A summary command establishes a seven-day repetition, adding daily offerings that cleanse and dedicate the altar as the process continues.
Verse by Verse
Seven-day installation for Aaron and his sons The instruction begins by pointing back to earlier directions: the installer must do everything “according to all that I have commanded you.” The main new detail is the timetable: the consecration of Aaron and his sons is not a single moment but a seven-day process.
Daily bull offering and daily altar cleansing Each day of the seven, a bull is offered as a sin offering “for atonement.” The verse ties that offering to the altar itself: at the time atonement is made, the altar is cleansed. Then the altar is also anointed, with the purpose of making it holy.
Seven-day atonement for the altar and resulting holiness The command repeats the seven-day frame, now explicitly applied to the altar: atonement is made for it and it is sanctified. The stated result is a new status—“the altar shall be most holy.” A final consequence is added: anything that touches the altar becomes holy, indicating that the altar’s set-apart status affects contact with it.
Literary Context
These verses conclude a larger set of instructions about installing Aaron and his sons as priests (Exodus 29:1–37), part of the tabernacle directions given at Sinai (Exodus 25–31). The immediate context has already described specific offerings, garments, washing, anointing, and the “filling of hands” for priestly service. Verses 35–37 function like a summary and schedule: they repeat the “as commanded” emphasis, set the duration at seven days, and add focused attention to the altar’s status—moving from something that must be cleansed to something considered “most holy,” with a stated effect on whatever touches it.
Historical Context
The setting assumes an Israelite community newly organized around a portable sanctuary in the wilderness period after leaving Egypt and arriving at Sinai. The passage reflects a world where ritual objects, spaces, and personnel had to be prepared before public worship could proceed in a stable, repeatable way. A seven-day cycle would be an easily recognized complete period for establishing a new role and a new working space. The altar is treated not merely as equipment but as a focal point of ongoing sacrifices, so its preparation is described with repeated daily actions and with language that marks boundaries—who or what can come into contact with it once it is dedicated.
Theological Significance

Exodus 29:35–37 closes the priest-installation instructions by stressing two linked things: a full seven-day process for Aaron and his sons, and a parallel seven-day process focused on the altar. The text is explicit that these actions are to be done “according to all that I have commanded,” highlighting careful conformity rather than improvisation.
The passage also presents “atonement” and “sanctifying” as actions applied not only to people but also to sacred space and equipment. The altar is cleansed, anointed, and set apart until it reaches a stated status: “most holy.”
1) What “whatever touches the altar shall be holy” includes. Some read it broadly: anything that comes into contact with the altar (objects and people) becomes holy in the sense of being set apart. Others read it more narrowly: the phrase mainly regulates objects associated with sacrifice (tools, offerings), and if a person touches it, the point is not that they become morally better but that contact places them under holy-space rules.
2) What “becomes holy” means in practice. One reading treats this as a real transfer of holiness from the altar to what touches it. Another sees it as a boundary-marker: contact designates something as belonging to the sacred sphere, meaning it must be treated as dedicated/restricted, not ordinary.
3) How the daily bull offering relates to altar cleansing. Some take the verse as describing one integrated rite: the bull sin offering is the means by which atonement and cleansing happen for the altar. Others distinguish steps: the bull is offered for atonement, and alongside that, additional cleansing/anointing actions are performed for the altar.
The text states outcomes (“shall be holy”) more than it explains mechanisms. It also uses the same family of words for atonement/sanctifying across different targets (priests and altar), leaving readers to infer whether the effect is best described as transfer, reclassification for sacred use, or both. The line “whatever touches” is also brief, so readers debate its scope.
Textually, the passage contributes a structured picture of how Israel’s worship system is launched: (1) installation of priests takes time and repetition (seven days), (2) sacrifice and “atonement” are connected to preparing both people and the altar, and (3) the altar ends the process with a heightened status (“most holy”) that changes how contact with it is understood and regulated.
