'Serpents' in the Bible

'Lo, I do send you forth as sheep in the midst of wolves, be ye therefore wise as the serpents, and simple as the doves.

'Serpents! brood of vipers! how may ye escape from the judgment of the gehenna?

serpents they shall take up; and if any deadly thing they may drink, it shall not hurt them; on the ailing they shall lay hands, and they shall be well.'

lo, I give to you the authority to tread upon serpents and scorpions, and on all the power of the enemy, and nothing by any means shall hurt you;

neither may we tempt the Christ, as also certain of them did tempt, and by the serpents did perish;

for their authorities are in their mouth, and in their tails, for their tails are like serpents, having heads, and with them they do injure;
