And the LORD said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live.
He rescued them many times, but they continued to rebel deliberately and were beaten down by their sin.
When He heard their cry, He took note of their distress,
remembered His covenant with them, and relented according to the abundance of His faithful love.
The LORD is gracious and compassionate, slow to anger and great in faithful love.
