Psalm 119 is divided into sections, each of which begins with a letter of the Hebrew alphabet. The fourth section begins with the letter Daleth (ד d). The word “cleaveth” in the verse “My soul cleaveth unto the dust” means to be glued to; to stick fast. According to some interpretations, the letter Daleth represents the poor person. The word Daleth means “door” or “gate” in Hebrew.
It reads in Psalm 119:25-32 NIV: ד Daleth “Door.”

I am laid low in the dust; preserve my life according to your word. I gave an account of my ways and you answered me; teach me your decrees. Cause me to understand the way of your precepts, that I may meditate on your wonderful deeds. My soul is weary with sorrow; strengthen me according to your word. Keep me from deceitful ways; be gracious to me and teach me your law. I have chosen the way of faithfulness; I have set my heart on your laws. I hold fast to your statutes, Lord; do not let me be put to shame. I run in the path of your commands, for you have broadened my understanding.
