'Word of the Lord' in the Bible

The child Samuel ministered to the LORD before Eli. The word of the LORD was rare in those days; there was no frequent vision.

Now Samuel did not yet know the LORD, neither was the word of the LORD yet revealed to him.

The LORD appeared again in Shiloh; for the LORD revealed himself to Samuel in Shiloh by the word of the LORD.

Then the word of the LORD came to Samuel, saying,

For rebellion is as the sin of witchcraft, and stubbornness is as idolatry and teraphim. Because you have rejected the word of the LORD, he has also rejected you from being king."

Samuel said to Saul, "I will not return with you; for you have rejected the word of the LORD, and the LORD has rejected you from being king over Israel."
