Halleluyah – Praise the LORD (הַלְּלוּיָהּ) "Let everything that has breath praise Yahweh.  Halleluyah" (Psalm 150:6). There are two parts here: "praise us" (הַלְּלוּ, hallel-oo) and "yah" (the short name of God, Yahweh). Interestingly, hallel's root (הָלַל) means "to shine" or "make a clear sound." Thus, our praise should be like a "clear and obvious boasting", "make a show", and even (for the youth) "to rave" about Him!
