And you shall make two golden rings for it. Under its molding on two opposite sides of it you shall make them, and they shall be holders for poles with which to carry it. You shall make the poles of acacia wood and overlay them with gold.
Exodus 30:4-5 ESV

The incense altar only has 2 rings for its carry-poles instead of 4. Only about waist height, it is the smallest and lightest of the Tabernacle furnishings, but the requirement for carry-poles indicates that it is still not to be treated like baggage in the wilderness wanderings. Just like the Ark of the Covenant, it is to be carried on the shoulders of four men, not on a wagon or in a pack. Our prayers to God and worship are sacred and should be treated as sacred.
