Jonah 2:3

“For you cast me into the depth,

In the heart of the seas,

And the flood was round about me,

All your waves and your billows passed over me.”

His remembrance of his experience was vivid. He had been cast into the heart of the sea, and had felt as though he was being swallowed up by the sea, almost as though he had been in his grave, with the waters sweeping over him. Note his emphasis on the fact that it was YHWH Who had done this to him, and that it was His waves and billows which passed over him. YHWH had been with him in all that had happened.
