Hallelujah

According to Wikipedia
"For most Christians, "Hallelujah" is considered the most joyful word of praise to God, rather than an injunction to praise Him."
Also,"it is a transliteration of the Hebrew word הַלְּלוּיָהּ (Standard Hebrew Halləluya, Tiberian Hebrew Halləlûyāh) meaning "[Let us] praise (הַלְּלוּ) Jah (Yah) (יָהּ)" (Sometimes rendered as "Praise (הַלְּלוּ) [the] LORD (יָהּ)or God")."

I actually was trying to write some post, when I googled the spelling of the word. Hmm ... I wonder if it is actually originated from Arabic! It sounds alot like derivative of the word tahleel: saying La Ilah illa Allah. Cuz the past tense of tahleel is (hallala) ..
Interesting!
Hallelujah!
