'Pretend' in the Bible

Jonadab advised him, "Lie down and pretend to be sick. When your father visits you, ask him, "Please let my sister Tamar come and give me something to eat that she prepares especially for me, and after she makes dinner for me, let her feed it to me personally.'"

Meanwhile, the LORD had spoken to Ahijah, "Be on your guard! Jeroboam's wife is coming to ask you about her son, because he is ill. You're to say such and such to her. When she arrives, she will pretend to be someone else!"

It's better to be unimportant, yet have a servant, than to pretend to be important, but lack food.

Don't magnify yourself in the presence of a king, and don't pretend to be in the company of famous men,

"Son of Man, tell Tyre's Commander-in-Chief, "This is what the Lord GOD says: "Because your heart is arrogant, and because you keep saying, "I have taken my seat, I am a god, seated in God's seat right in the middle of the sea,' and because you're a man, and not a god, even though you pretend that you have a god-like heart"
