As the one praying on the mountaintop, Moses typifies Christ, but as the one whose hands became heavy, Moses represents us. This signifies that while Christ is praying in the heavens, we too need to pray on earth (1 Tim. 2:8). Because the flesh never changes or improves, in order to prevail against the flesh, we need to pray without ceasing (1 Thes. 5:17; Col. 4:2), joining ourselves to Christ in His intercession. However, often our praying hands become heavy. Thus, we need a stone to support us, and we need the help of Aaron and Hur. The stone, a solid base for our prayer life, refers to our realization that in ourselves we are weak and that in order to sustain our prayer, we need Christ to be our support (cf. John 15:5b). Aaron, the high priest (Exo. 28:1; Heb. 5:1, 4), signifies the priesthood, and Hur, who was of the tribe of Judah (Exo. 31:2), signifies the kingship (Gen. 49:10). The priesthood is related to the Holy of Holies, which in our experience is always related to our spirit (Heb. 10:19 and note Heb. 10:191b). Hence, to sustain our prayer and to thus defeat the flesh, we need the priesthood to strengthen our spirit. We also need to be obedient to the Lord under His authority, the kingship. Furthermore, Hur is related to the building of the tabernacle (Exo. 31:2-5), and the direction of Exodus is toward this goal. This indicates that we need to take the building of the church as the goal of our prayer.
