What does the Bible say about the oil for the lamps in the tabernacle?

In Exodus 27:20-21, God commanded the Israelites to bring pure olive oil for the lamps in the tabernacle. This oil must be pure and beaten, symbolizing the Holy Spirit's role in providing light to believers. The purity of the oil reflects the holiness of the Holy Spirit, as He is the third person of the Trinity, fully God and without sin. Just as the oil needed to be kept burning continually to provide light in the tabernacle, the Holy Spirit continuously illuminates the hearts of believers, enabling them to live in righteousness and truth.
