Part of God's covenant promise after the flood that seasonal cycles will continue perpetually. Paired with heat, cold represents the reliable alternation of seasons that makes agriculture and life possible. This isn't theological cold - it's meteorological, the winter chill that balances summer warmth. God's promise of 'cold and heat' while earth remains is a charter for natural order, assuring Noah that despite judgment, creation's rhythms will continue. Farmers can plant knowing seasons will follow their course. This simple promise - that cold will follow heat and heat will follow cold - underwrites all human planning and hope.
