'Word of Truth' in the Bible

And take not the word of truth utterly out of my mouth; For I have hoped in thine ordinances.

in the word of truth, in the power of God; by the armor of righteousness on the right hand and on the left,

Give diligence to present thyself approved unto God, a workman that needeth not to be ashamed, handling aright the word of truth.

Of his own will he brought us forth by the word of truth, that we should be a kind of firstfruits of his creatures.
