'Word of the Lord' in the Bible

As for God, His way is blameless.The word of the Lord is tested [it is perfect, it is faultless];He is a shield to all who take refuge in Him.

For the word of the Lord is right;And all His work is done in faithfulness.

By the word of the Lord were the heavens made,And all their host by the breath of His mouth.

Until the time that his word [of prophecy regarding his brothers] came true,The word of the Lord tested and refined him.
