Genesis 27:33 New International Version (NIV)
33 Isaac trembled violently and said, “Who was it, then, that hunted game and brought it to me? I ate it just before you came and I blessed him—and indeed he will be blessed!”
In these ancient times, a person’s word was binding. The word of a person in these times was like a contract is to us today. A contract is binding. The word of a person in ancient times was binding. This was even more so with a formal oath. Isaac’s blessing was a formal oath and this oath was irrevocable. Is your word your bond today? It is important to keep to your word and do what you say you will do. Do not get into the habit of not keeping your word. Get in the habit of keeping your word and doing what you say you stated you would do.
