The answer is: Two cherubim

Exo 25:18

The Ark of the Covenant is one of the most striking symbols in the Hebrew Scriptures, embodying both divine presence and the covenant between God and the Israelites. Found atop the ark were two intricately crafted cherubim, angelic beings that, in biblical literature, often represent God's majesty and mystery.

These cherubim faced each other with wings outstretched, overshadowing the "Mercy Seat," which served as a throne for God’s presence among His people. You'll find a fascinating connection here—cherubim may remind us of similar beings in other ancient Near Eastern cultures, like the sphinx of Egypt, showing how these heavenly figures tied the Israelite faith to broader cultural themes.

Interestingly, the term “Mercy Seat” is rich with meaning. In Hebrew, it’s "kapporet," which signifies a cover or reconciliation. This speaks to not just God’s judgment but also His grace, where mercy and atonement come together. During Yom Kipur, or the Day of Atonement, the high priest would sprinkle blood here as part of the ritual, acting as a powerful reminder of forgiveness and renewal.

Cheekily fun fact: if angels had an interior design style, the cherubim on the Ark probably set quite the high bar! Their stunning presence reminds us that even divine things can lean toward the beauty and artistry of creation. So, the cherubim aren't just building theologically fascinating concepts—they're making sure even the throne of God has a stunning view.
