"Could not understand"

1. Jacob 4: 14
   14 But behold, the Jews were a ^astiffnecked people; and they ^bdespised the words of ^cplainness, and ^dkilled the prophets, and sought for things that they could not understand. Wherefore, because of their ^eblindness, which ^fblindness came by looking beyond the ^gmark, they must needs fall; for God hath taken away his plainness from them, and delivered unto them many things which they ^hcannot understand, because they desired it. And because they desired it God hath done it, that they may ⁱstumble.
2. Mosiah 26: 1, 3
   1 Now it came to pass that there were many of the rising generation that could not understand the ^awords of king Benjamin, being little children at the time he spake unto his people; and they did ^bnot believe the tradition of their fathers.

   3 And now because of their ^aunbelief they could not ^bunderstand the word of God; and their hearts were hardened.
3. D&C 50: 15
   15 And then received ye ^aspirits which ye could not understand, and received them to be of God; and in this are ye justified?
