'Understanding' in the Bible

All who heard Him were amazed by His intelligence and His understanding and His answers.

And Jesus kept increasing in wisdom and in stature, and in favor with God and men.

But the scribes and Pharisees were filled with senseless rage [and lacked spiritual insight], and discussed with one another what they might do to Jesus.

In that very hour He was overjoyed and rejoiced greatly in the Holy Spirit, and He said, “I praise You, O Father, Lord of heaven and earth, that You have hidden these things [relating to salvation] from the wise and intelligent, and have revealed them to infants [the childlike and untaught]. Yes, Father, for this way was [Your gracious will and choice, and was] well-pleasing in Your sight.
