'Knocking' in the Bible

They set your sanctuary on fire; they desecrate your dwelling place by knocking it to the ground.

W I sleep, but my heart is awake.A sound! My love is knocking!M Open to me, my sister, my darling,my dove, my perfect one.For my head is drenched with dew,my hair with droplets of the night.

Then all the color drained from the king's face and he became alarmed. The joints of his hips gave way, and his knees began knocking together.

She is emptied! Yes, she is desolate and waste!Hearts are melting and knees knocking!Also anguish is in the whole bodyAnd all their faces are grown pale!
