Psalm 1 opens with a word that begins with aleph א — the first letter of the Hebrew alphabet. It closes with a word that begins with tav ת — the last letter.
A psalm about walking the full length of a faithful life is arranged to span the full length of the alphabet. The form enacts the content. There is nothing outside the scope of YHWH’s instruction, and the poem signals this by beginning at the beginning and ending at the ending.
