'Wallowing' in the Bible

Now Amasa [was] wallowing in the blood in the middle of the highway; when the man saw that all the people stood [there], he turned Amasa over from the highway into the field, and he threw a garment over him because he had seen that all who had come by him had stopped.

The [statement] of the true proverb has happened to them, "A dog returns to its own vomit," and "A sow, [after] washing herself, [returns] to wallowing in the mud."
