1 Chronicles 28:18 (KJV) says, "And for the altar of incense refined gold by weight; and gold for the pattern of the chariot of the cherubims, that spread out their wings, and covered the ark of the covenant of the Lord."

The book of 1 Chronicles is a historical narrative that covers the history of Israel from Adam to the Babylonian exile. In this chapter, King David is giving a speech to the leaders of Israel before his death, in which he outlines the plans for the temple that his son Solomon will build for the Lord. In this verse, David is specifying the materials and design for the altar of incense and the chariot of the cherubim, which are important elements of the temple.

The mention of refined gold in this verse symbolizes the purity and holiness of the temple. Gold is a precious metal often associated with royalty and divinity, and in the context of the temple, it represents the value and sacredness of the space where God's presence would dwell. The use of refined gold emphasizes the importance of using only the best materials for the construction of the temple, as it is a place dedicated to the worship of the Lord.

The altar of incense mentioned in this verse was a key fixture in the temple, where priests would burn incense as an offering to God. The smoke from the incense was believed to carry the prayers of the people to heaven, symbolizing the connection between God and his people. By specifying the use of refined gold for the altar, David is emphasizing the significance of this act of worship and the need for it to be carried out with the utmost reverence and purity.

The chariot of the cherubim, which is also mentioned in this verse, is a reference to the design of the ark of the covenant. The cherubim are angelic beings often associated with the presence of God, and the chariot design symbolizes the throne of God. The use of gold for this pattern highlights the divine nature of the ark and the importance of honoring God's presence within the temple.

Overall, this verse reflects the themes of reverence, holiness, and the divine presence of God. The detailed instructions for the construction of the temple emphasize the importance of honoring and worshiping God with the best of what we have to offer. The use of refined gold for the altar and the chariot of the cherubim symbolizes the purity and sacredness of the temple, as well as the value of the worship and prayer that take place within its walls.

In a broader context, this verse also reminds believers of the importance of approaching God with reverence and humility. Just as the materials for the temple were carefully chosen and used in a specific way, so too should our worship and devotion to God be intentional and pure. The emphasis on refined gold serves as a reminder to cherish and honor the presence of God in our lives, and to offer our prayers and worship with the utmost sincerity and devotion.

In conclusion, 1 Chronicles 28:18 provides valuable insight into the construction and significance of the temple in ancient Israel, as well as the broader themes of reverence and devotion in our relationship with God. The use of refined gold for the altar of incense and the chariot of the cherubim symbolizes the purity and sacredness of the temple, serving as a reminder to approach God with reverence and devotion in our own lives.
