Exodus 29:35
And thus shalt thou do unto Aaron, and to his sons, according to all things which I have commanded thee: seven days shalt thou consecrate them.
Exodus 29:35 (KJV)
Context
Exodus 29 records God’s detailed instructions to Moses for consecrating Aaron and his sons as priests. This verse is the concluding command in that section, summarizing the entire ceremony. The rituals included washing, clothing, anointing, offering sacrifices, and applying blood to the priests and their garments. These acts set the priests apart for holy service before the Lord. The consecration was a critical step in establishing the priesthood within the nation of Israel.
Meaning
The phrase “according to all things which I have commanded thee” stresses that no part of God’s instruction was to be omitted. Moses was to follow every detail exactly. The seven days of consecration were not arbitrary; they formed a deliberate, extended period of setting apart. This length of time showed the seriousness and holiness required for those who would serve before God. The word “consecrate” means to dedicate someone or something as holy and sacred. During these seven days, Aaron and his sons underwent specific ceremonies and sacrifices to sanctify them for their priestly duties. The detailed nature of the command shows that God cares about the manner in which He is approached and served.
Biblical connections
The fulfillment of these commands is recorded in Leviticus 8:1-36, where Moses carefully and punctually observed all that God had instructed. This connection shows that God’s word was not merely spoken but carried out in practice. The New Testament also applies the idea of being set apart to all believers. First Peter 2:9 calls Christians a “royal priesthood,” called to live holy lives dedicated to God’s purposes. Jesus also taught the importance of obedience in John 14:15, saying, “If you love me, keep my commandments.” These passages together show that the principle of consecration and obedience continues into the new covenant.
Application
This verse teaches that service to God is not casual. It requires thorough, God-ordained preparation. Believers today are called to obey God’s instructions fully, not selectively. The seven days of consecration picture a complete period of preparation, reminding us that spiritual growth and readiness for service often take time and deliberate focus. Just as Aaron and his sons were set apart for a unique calling, each believer has a specific role in God’s service. We should embrace our responsibilities as sacred opportunities to honor Him.
Holiness and sanctification: God calls His people to be set apart for His purposes, living with purity and devotion.
Obedience to God’s Word: Following God’s commands demonstrates love for Him and submission to His will.
Preparation and waiting: Seasons of preparation are necessary before stepping into significant responsibilities or ministries.
Special calling and service: God assigns each believer unique gifts and roles, and these are to be treated as holy.
Reflection
The detailed nature of God’s command shows that He cares about how He is approached and served. The consecration of Aaron and his sons was not a brief ritual but a week-long dedication. This challenges us to examine our own approach to God. Are we willing to undergo the process of sanctification, or do we seek shortcuts? The verse assures us that God equips those He calls, and He honors those who follow His instructions with patience and faith. The seven days remind us that being set apart for God’s service involves a process of dedication that cannot be rushed.
