In Psalm 119:73-80, Yodh is defined as a “hand” or “arm”. Its form suggests a hand reaching toward heaven in prayer. Yodh is the smallest Hebrew letter. The letter Yodh is the tenth letter of the Hebrew alphabet and relates closely to the word Yid, which means Jew. It also represents the number 10, but subsequent letters after this are multiples of 10 (and so there is no one letter for 11).
It reads in Psalm 119:73-80 NIV: י Yodh
Your hands made me and formed me; give me understanding to learn your commands. May those who fear you rejoice when they see me, for I have put my hope in your word. I know, Lord, that your laws are righteous, and that in faithfulness you have afflicted me. May your unfailing love be my comfort, according to your promise to your servant. Let your compassion come to me that I may live, for your law is my delight. May the arrogant be put to shame for wronging me without cause; but I will meditate on your precepts. May those who fear you turn to me, those who understand your statutes. May I wholeheartedly follow your decrees, that I may not be put to shame.
