Srimad Bhagavatam Canto 10, Chapter 50, Text 20

SB 10.50.20

sri-suka uvaca
jara-sutas tav abhisrtya madhavau
 maha-balaughena baliyasavrnot
sa-sainya-yana-dhvaja-vaji-sarathi
 suryanalau vayur ivabhra-renubhih
 
Translation: 
 
Sukadeva Gosvami said: Just as the wind covers the sun with clouds or a fire with dust, the son of Jara marched toward the two descendants of Madhu and with his huge assemblage of armies surrounded Them and Their soldiers, chariots, flags, horses and charioteers.
 
Purport: 
 
Acarya Sridhara points out that clouds only seem to cover the sun: the sun remains shining in the vast sky. Nor is the potency of fire affected by a thin covering of dust. Similarly, the “covering” of Jarasandha’s military strength was only apparent.
