Psalm 119 is the longest Psalm and the longest chapter in the Bible.
There are 22 letters in the Hebrew alphabet, and this Psalm contains 22 stanzas of 8 verses each. It is arranged in an acrostic pattern; each of the 22 sections is given to a letter of the Hebrew aleph-bet, and each line in that section begins with that letter.
This is a Psalm glorifying God and His Word, it refers to Scripture over and over again.
This Psalm is remarkable for how often it refers to God’s written revelation, His word.
