'Discerning' in the Bible

youths in whom was no defect, who were good-looking, showing intelligence in every branch of wisdom, endowed with understanding and discerning knowledge, and who had ability for serving in the king’s court; and he ordered him to teach them the literature and language of the Chaldeans.

It is God who alters the times and seasons, and he removes kings and promotes kings. He gives wisdom to the wise and knowledge to the discerning.
