“Then the Lord said to Moses, “Make a fiery serpent, and set it on a standard; and it shall come about, that everyone who is bitten, when he looks at it, he will live.”” Numbers 21:8
The “complaining spirit” of the Jews strikes again! We are told “the people became impatient because of the journey”, they impugned Moses, and complained about the Manna! So, “The Lord sent fiery serpents…, so that many people of Israel died.” As the people repented, today’s verse was God’s Remedy. Jesus used this Image when he spoke with Nicodemus. Consider; the People knew they had sinned and were under Judgement; the Cure (the Gospel) was declared to them; if they Believed and Obeyed it, they would be Healed (Saved).
Amazing, isn’t it? Old Testament version of John 3!
