Sirach 43:2
Ben Sira, Ecclesiasticus1 The pride of the higher realms is the clear vault of the sky, as glorious to behold as the sight of the heavens. 2 The sun, when it appears, proclaims as it rises what a marvelous instrument it is, the work of the Most High. 3 At noon it parches the land, and who can withstand its burning heat? 4 A man tending a furnace works in burning heat, but three times as hot is the sun scorching the mountains; it breathes out fiery vapors, and its bright rays blind the eyes.
1 Enoch 4:1
1 And again, observe ye the days of summer how the sun is above the earth over against it. And you seek shade and shelter by reason of the heat of the sun, and the earth also burns with growing heat, and so you cannot tread on the earth, or on a rock by reason of its heat.

"... A description of the signs of the (four) seasons is included at the end of the Astronomical Book. Outside the Enochic texts, Sirach 43:2-4 contains a description of the sun's heat and its effect on the earth that parallels I Enoch 4:1. When it is viewed in the light of these materials, the present section indicates that its author has crafted traditional material with purpose and symmetry ..."
