Luke 2:40 FNV

Other children have foolishness bound in their hearts, which appears in what they say or do, but he was filled with wisdom, by the influence of the Holy Ghost; every thing he said and did, was wisely said and wisely done, above his years. Other children show the corruption of their nature; nothing but the grace of God was upon him.

[Taken from Matthew Henry's Concise Commentary]

The Child grew strong in his spirit and was filled with wisdom, for the blessing of the Great Spirit was resting on him. (Luke 2:40)
