Tov is the Hebrew word for good — and it rings out at the very beginning of the Bible. Again and again through the creation account, God saw that it was tov, and at the end, behold, it was very tov. Tov means more than morally correct; it means good in the fullest sense: beautiful, pleasing, life-giving, as things ought to be.
This word shapes how the Bible sees the world: creation is fundamentally good because a good God made it. O taste and see that the LORD is tov, sings the psalmist. Even after sin marred the world, God's goodness remains the deepest truth about him — and the promise that goodness and mercy shall follow us all our days rests on the fact that God himself is tov.
Tov in Scripture
And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
