Deuteronomy 3:25-26 [3:25] I pray thee, let me go over, and see the good land that is beyond Jordan, that goodly mountain, and Lebanon. [3:26] But the LORD was wroth with me for your sakes, and would not hear me: and the LORD said unto me, Let it suffice thee; speak no more unto me of this matter. (God said "no" to Moses)
II Corinthians 12:7-9 [12:7] And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure. [12:8] For this thing I besought the Lord thrice, that it might depart from me. [12:9] And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. (God said "no" to Paul)
