Exodus 15:9
8 By the blast of your nostrils the waters were piled up, the flowing water stood upright like a heap, and the deep waters were solidified in the heart of the sea. 9 The enemy said, ‘I will chase, I will overtake, I will divide the spoil; my desire will be satisfied on them. I will draw my sword, my hand will destroy them.’ 10 But you blew with your breath, and the sea covered them. They sank like lead in the mighty waters.
Leviticus 26:33
