Meshach (me-shack) is the name given in Babylon to Mishael, one of the three young hebrew companions of Daniel (Daniel 1:7; 2:49; 3:12-30). It is likely based on a name of a Chaldean (Babylonian) god. It also means "to feed" or "to provide" (as in how a husband would provide for his family) in Hebrew.
Meshach (possibly, Mi·sha·aku), apparently a clever twist of "Who Is Like God?" to "Who Is What Aku Is?"
