I Samuel 24:3

3 Chegou a uns currais de ovelhas no caminho, onde havia uma caverna. Saul entrou nela, para fazer as suas necessidades. Ora, Davi e os seus homens estavam sentados no mais interior da caverna.

3 And on the way he came to a place where sheep were kept, where there was a hollow in the rock; and Saul went in for a private purpose. Now David and his men were in the deepest part of the hollow.
