Mattityahu 11:25-26

At that time, Rebbe, Melech HaMoshiach said, Modeh Ani, Avi, Adon HaShomayim v'HaAretz, (I thank you, Father, L-rd of Heaven and Earth), because you hid these things from the chachamim (wise) and those with seichel, and to them they are nistar (hidden, esoteric), and you made a hisgalus (revelation) of them unto ollelim (infants). Ken, Avi, for thus it was pleasing in your sight.
