'Well informed' in the Bible

Kenaniah, the leader of the Levites, was in charge of transport, for he was well-informed on this matter;

Keep well informed of the condition of your flocks and pay attention to your herds,

I again saw under the sun, that not, to the swift, was the race, nor, to the strong, the battle, nay! nor, to the wise, food, nor yet, to the intelligent, riches, nor, even to the well-informed, comeliness, - for, time and accident, happened to them all.

Felix was rather well informed about the Way, and so he adjourned the trial with the comment, "When Tribune Lysias arrives, I'll decide your case."

For this ye are well informed of, knowing that no fornicator, or unclean person, or person of unbridled lust, who is an idolater, has inheritance in the kingdom of the Christ and God.
