Sink deep

1. Ps. 69: 2
   2 I sink in deep mire, where there is no standing: I am come into deep waters, where the floods overflow me.
2. Enos 1: 3
   3 Behold, I went to hunt beasts in the forests; and the words which I had often heard my father speak concerning eternal life, and the joy of the saints, sunk deep into my heart.
