Job 37:15-17

New Revised Standard Version Catholic Edition

¹⁵ Do you know how God lays his command upon them,
    and causes the lightning of his cloud to shine?
¹⁶ Do you know the balancings of the clouds,
    the wondrous works of the one whose knowledge is perfect,
¹⁷ you whose garments are hot
    when the earth is still because of the south wind?
