'Concealed' in the Bible

For nothing is concealed that won’t be revealed, and nothing hidden that won’t be made known and come to light.

But they did not understand this statement; it was concealed from them so that they could not grasp it, and they were afraid to ask Him about it.

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.

Woe to you! For you are like concealed tombs, and the people who walk over them are unaware of it.”

But nothing is concealed that will not be revealed, and secret that will not be made known.

And they understood none of these [things], and this saying was concealed from them, and they did not comprehend the things that were said.
