A cubit shall be the length thereof, and a cubit the breadth thereof; foursquare shall it be: and two cubits shall be the height thereof: the horns thereof shall be of the same.

EXODUS 30:2KJV
Know the Bible

What does Exodus 30:2 mean?

Exodus 30:2 gives the exact measurements and shape for the altar of incense: it should be one cubit long, one cubit wide, and two cubits high, making it a square shape with horns at each corner, all made as one piece. This verse is part of God’s instructions to Moses about how to construct this special altar for use in the tabernacle.

In this passage, God is speaking directly to Moses on Mount Sinai, providing detailed directions for building the altar that would stand in the Holy Place. The “horns” refer to projections at the corners, which were a common feature on altars in the ancient world. The focus on precise measurements and design shows the importance of following God’s instructions exactly in the worship practices of Israel.

The Hebrew behind Exodus 30:2

  • Cubit (אַמָּה, 'ammah'): This word refers to an ancient unit of length, roughly the distance from the elbow to the tip of the middle finger—about 18 inches (45 cm). Knowing this helps modern readers picture the altar’s actual size.
  • Foursquare (רָבוּעַ, rabu'a): This means the altar was perfectly square on top, not rectangular. The shape emphasizes symmetry and order in the design.
  • Horns (קֶרֶן, qeren): These are the corner projections, made as part of the altar itself. In Israelite worship, horns often symbolized strength and were sometimes used in rituals.

Why Exodus 30:2 matters

  • The verse shows that the altar was not a random or improvised object, but carefully designed according to God’s specifications, highlighting the seriousness of worship in Israel’s life.
  • By specifying the altar’s size and shape, the verse helps readers understand how the tabernacle was organized and how each object had a set place and purpose.
  • The mention of the “horns” connects this altar to other biblical altars, where the horns sometimes played a role in rituals of atonement or sanctuary, giving insight into later stories and laws.
