'Spend the Night' in the Bible

David pleaded [with] God on behalf of the boy and David fasted. He went to spend the night and lay upon the ground.

Hushai continued, "You know your father and his men, that they [are] mighty warriors and they {are enraged} as a bear robbed of [her] offspring in the field. Your father [is] a man of war, so he will not spend the night with the troops.

So then, send quickly and tell David, 'Don't spend the night at the fords of the wilderness! Moreover, by all means cross over lest the king and all the people who [are] with him be swallowed up.'"
