Why did the princes of this world crucify the Lord of glory?
The princes of this world crucified the Lord of glory because they did not know the hidden wisdom of God, the wisdom ordained before the world unto glory. Had they known it, they would not have crucified Him. Their ignorance of God's mystery explains their action.
Les explains that Paul writes in 1 Corinthians 2:7-8 about the wisdom of God in a mystery, the hidden wisdom God ordained before the world unto glory. This wisdom was revealed to the apostle Paul, but none of the princes of this world knew it. Because they did not know it, they crucified the Lord of glory. Les points out that had they known it, they would not have crucified Him. The context stresses that God had hidden these things, and Paul uses the plural pronoun while speaking of himself.
Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
