Yes, the stork in the sky knows her appointed times; and the turtledove and the swallow and the crane observe the time of their coming; but my people do not know the LORD's law.

And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
