The Greek verb heilissō means to roll up or roll together — as one rolls a scroll. In the New Testament it appears in Hebrews 1:12 in a quotation from Psalm 102:26, describing the transience of the created order compared to the eternal nature of the Son of God.
The author of Hebrews quotes Psalm 102:26 — 'like a robe you will roll them up (heilissō), like a garment they will be changed' — applying it to the Son to demonstrate His superiority over the created order. The heavens themselves, which seem so permanent and vast, will be rolled up like a worn garment and replaced. Only the Son remains the same, 'yesterday, today, and forever' (Hebrews 13:8). This temporal contrast undergirds the call to hold fast to Christ rather than to the passing world.
