I believe that there are things concealed in scripture yet to be discovered. It is the nature of God' s word. (Proverbs 25:2).
When Proverbs was written, the fullness of God's revelation through Jesus Christ had not yet occurred. You're using that verse almost to deny Scripture as a matter of General Revelation (i.e., Truth revealed to all).
When something new causes us to examine our doctrine, we cannot measure how much departure it causes to determine if it is OK.
This sentence is a bit opaque.
When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power. But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight. And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven. Then returned they unto Jerusalem from the mount called Olivet, which is from Jerusalem a sabbath day's journey.
