'Upright' in the Bible

Should [this] be said, O house of Jacob? Is the patience of Yahweh shortened? [Are] these his deeds? Are my words not pleasing to him who walks upright?

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 perished out of the earth: and there is none upright among men: they all lie in wait for blood; they hunt every man his brother with a net.

The best of them is as a brier: the most upright is sharper than a thorn hedge: the day of thy watchmen and thy visitation cometh; now shall be their perplexity.
