“The LORD said to Moses, ‘Make a venomous snake, and set it on a pole. It shall happen, that everyone who is bitten, when he sees it, shall live.’  Moses made a serpent of brass, and set it on the pole. If a serpent had bitten any man, when he looked at the serpent of brass, he lived”. – Numbers 21:8-9

“And you will model two great winged creatures of beaten gold; you will make them at the two ends of the mercy-seat. Model one of the winged creatures at one end and the other winged creature at the other end; you will model the winged creatures of a piece with the mercy-seat at either end. The winged creatures must have their wings spread upwards, protecting the mercy-seat with their wings and facing each other, their faces being towards the mercy-seat. You will put the mercy-seat on the top of the ark and inside the ark you will put the Testimony which I am about to give you. There I shall come to meet you; from above the mercy-seat, from between the two-winged creatures which are on the ark of the Testimony, I shall give you all my orders for the Israelites.”– Exodus 25:18 - 22
