'Smooth' in the Bible

Which sends its representatives by the sea, even in ships of papyrus on the waters. Go back quickly, O representatives, to a nation tall and smooth, to a people causing fear through all their history; a strong nation, crushing down its haters, whose land is cut through by rivers.

In that time an offering will be made to the Lord of armies from a people tall and smooth, causing fear through all their history; a strong nation, crushing down its haters, whose land is cut through by rivers, an offering taken to the place of the name of the Lord of armies, even Mount Zion.

The way of the good man is straight; the road of the upright is made smooth by you.

So the metal-worker put heart into the gold-worker, and he who was hammering the metal smooth said kind words to the iron-worker, saying of the plate, It is ready: and he put it together with nails, so that there might be no slipping.

Among the smooth stones of the valley is your heritage; they, even they, are your part: even to them have you made a drink offering and a meal offering. Is it possible for such things to be overlooked by me?
