'According to the Word of the Lord' in the Bible

So I bought a belt according to the word of the LORD, and put it on my waist.

So Hanamel my uncle's son came to me in the court of the prison according to the word of the LORD, and said unto me, Buy my field, I pray you, that is in Anathoth, which is in the country of Benjamin: for the right of inheritance is yours, and the redemption is yours; buy it for yourself. Then I knew that this was the word of the LORD.
