'Hidden' in the Bible

For nothing is secret that will not become evident, and nothing hidden that will never be known and come to light.

At [that] same time he rejoiced in the Holy Spirit and said, "I praise you, Father, Lord of heaven and earth, that you have hidden these [things] from the wise and intelligent and have revealed them to young children. Yes, Father, for this was pleasing before you.

saying, "If you had known on this day--even you--the things [that make] for peace! But now they are hidden from your eyes.
