How does Jesus' three years of public ministry parallel the three days the Passover lamb was inspected?
The Passover lamb was held three days for close inspection, looking for any blemish, and if found whole it could be sacrificed. Jesus' three-year public ministry placed Him under constant scrutiny by religious authorities and ordinary people; He was not hidden, yet no one could accuse Him of wrongdoing. He remained without spot, without blemish, and blameless.
Les explains that the Passover lamb was kept up for three days so the household could completely observe it, looking for any blemish, poor health, or anything wrong. If the lamb was still whole after those three days, it could be killed for the Passover sacrifice. He then applies the same pattern to Christ: Jesus spent three years going up and down the land of Israel, under complete scrutiny by the religious authorities and more or less by the ordinary man in the street. He was not hidden from anyone, yet no one could point a finger at Him and accuse Him of wrongdoing. He was without spot, without blemish, blameless. Thus the three days of observing the lamb parallel the three years of Christ's public ministry, in which He was examined and found perfect.
