That for incense, whereof see Exo_30:6, but here of a much larger size. See in chap. 12:1. This altar of wood, and four-square, was a type of Christ (not of the Cross), in whom our prayers come before God as incense, and He is the propitiation for our sins (1Jn_2:2; Exo_30:1; Psa_141:2; Rev_5:8). The largeness of this altar above that of old, showeth that the saints under the Gospel would make much more improvement of the Lord Jesus in prayer, and make use of His mediation and intercession by faith in their heavenly supplications, than the saints of old were ordinarily wont to do. (J. Trapp.)
