Jeremiah 8:5-7

Why then is this people of Jerusalem slidden back by a perpetual backsliding? they hold fast deceit, they refuse to return. I hearkened and heard, but they spake not aright: no man repented him of his wickedness, saying, What have I done? every one turned to his course, as the horse rusheth into the battle. Yea, the stork in the heaven knoweth her appointed times; and the turtle and the crane and the swallow observe the time of their coming; but my people know not the judgment of the LORD.
