The Aramaic verb pelach is the word used in Daniel for worship and religious service. It appears in contexts of serving God or idols — the three young men refusing to serve Nebuchadnezzar's golden image (Daniel 3), and the accusation that Daniel continued worshiping his God (Daniel 6). It is cognate with Hebrew palach (to cut/split open).
Pelach in Daniel 3 and 6 is the vocabulary of the ultimate choice: whom will you serve? Shadrach, Meshach, and Abednego refused to pelach the golden image even at cost of their lives (Daniel 3:12, 14, 17-18). Daniel continued to pelach his God three times daily despite the royal decree (Daniel 6:16, 20). Both stories establish that worship is worth dying for — and that God honors those who honor Him with exclusive devotion. The NT echo: "No one can serve two masters" (Matthew 6:24). The great question of every age is the same: pelach whom?
