'Upright' in the Bible

O my people, keep in mind now what was designed by Balak, king of Moab, and the answer which Balaam, son of Beor, gave him; the events, from Shittim to Gilgal, so that you may be certain of the upright acts of the Lord.

The good man is gone from the earth, there is no one upright among men: they are all waiting secretly for blood, every man is going after his brother with a net.

The best of them is like a waste plant, and their upright ones are like a wall of thorns. Sorrow! the day of their fate has come; now will trouble come on them.
