Mark 5:43

5:43 He strictly ordered that no one should know about this, ¹  and told them to give her something to eat.

Mark 7:36

7:36 Jesus ordered them not to tell anything. But as much as he ordered them not to do this, they proclaimed it all the more. ² 

Mark 9:9

9:9 As they were coming down from the mountain, he gave them orders not to tell anyone what they had seen until after the Son of Man had risen from the dead.

[5:43]  ¹ sn That no one should know about this. See the note on the phrase who he was in 3:12.

[7:36]  ² tn Grk “but as much as he ordered them, these rather so much more proclaimed.” Greek tends to omit direct objects when they are clear from the context, but these usually need to be supplied for the modern English reader. Here what Jesus ordered has been clarified (“ordered them not to do this”), and the pronoun “it” has been supplied after “proclaimed.”
