Today we did Epiphany and I got back to Sunday school after a six-week hiatus for a five minute Hebrew lesson. With several new children there I introduced the word Hallelujah as one Hebrew word that everyone would know. After my very short talk, the leader invited us to sing a Hallelujah to the tune and descant of 'Seek ye First'.
I used Psalm 117 as the introduction to this word because Psalm 117 invites all the world into the praises of the Psalter. See this post for the whole psalm. Our little wooden block book of the Psalter shows its name as תְהִלִּים Tehillim, prayers and praises. It is the largest book at 150 chapters but it contains the shortest chapter - Psalm 117.
