The Hebrew alphabet is made up of 22 letters, which are used to compose the Word of God. The word of God is called a lamp (Psalms 119:105, Proverbs 6:22), thus it is the light by which we are to live. The word light is found 264 times in Scripture. When 264 is divided by 12 (divine authority) we have twenty-two, which represents light. TAV (MARK or SIGN): The copies of All cosmic existence. They carry the likeness of their Father.
 

The Psalm is arranged in an acrostic pattern. There are 22 letters in the Hebrew alphabet, and this Psalm contains 22 units of 8 verses each. Each of the 22 sections is given to a letter of the Hebrew alphabet, and each line in that section begins with that letter. The closest parallel to this pattern in Scripture is found in Lamentations 3, which is also divided into 22 sections, and there are a few other passages in the Hebrew Scriptures which use an acrostic pattern.

Since this is a Psalm glorifying God and His Word, it refers to Scripture over and over again. The psalm is remarkable for how often it refers to God’s written revelation, His word. It is referred to in almost every verse.
