Augustine of Hippo
Though a tent may occasionally symbolize a space for tranquil living, interpreted more literally, it evokes the concept of conflict. Consequently, those who share this tent during battle are referred to as "tentmates." This notion is reinforced by the earlier question, "Who shall dwell?" As we engage in spiritual warfare against the adversary, the tent serves as our refuge and place of respite.
While the tabernacle might occasionally be perceived as a perpetual dwelling place, its true significance reveals it as a site of conflict. This is why soldiers are referred to as companions in tents, as they share their encampments. This interpretation aligns with the phrase, "Who shall wander?" For a period, we struggle against the adversary, and then we seek a tabernacle for rejuvenation. This specifically highlights the faith of the temporal family established for us during the earthly ministry of the Lord. And who shall find rest on Thy holy mountain? Perhaps here, he references both the eternal dwelling itself, as indicated in 2 Corinthians 5:1-2, suggesting that the mountain symbolizes the supreme nature of Christ's love in everlasting life.
