(in R.V., Isa 11:8; 14:29; 59:5; Jer 8:17), the "king serpent," as the name imports; a fabulous serpent said to be three spans long, with a spot on its head like a crown. Probably the yellow snake is intended. (See Cockatrice.)
And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the adder's den.
Rejoice not, O Philistia, all of thee, because the rod that smote thee is broken; for out of the serpent's root shall come forth an adder, and his fruit shall be a fiery flying serpent.
They hatch adders eggs, and weave the spider's web: he that eateth of their eggs dieth; and that which is crushed breaketh out into a viper.
