Not let know

1. Ex. 33: 12
     12 ¶ And Moses said unto the Lord, See, thou sayest unto me, Bring up this people: and thou hast not let me know whom thou wilt send with me. Yet thou hast said, I know thee by name, and thou hast also found grace in my sight.
2. Alma 35: 5
     5 Now their rulers and their priests and their teachers did not let the people know concerning their desires; therefore they found out privily the minds of all the people.
