'Word of the Lord' in the Bible

As for God, his way is perfect: the word of the LORD is tried: he is a buckler to all those that trust in him.

For the word of the LORD is right; and all his works are done in truth.

By the word of the LORD were the heavens made; and all the host of them by the breath of his mouth.

Until the time that his word came: the word of the LORD tried him.
