'Reliable' in the Bible

The Lord said to his people: "You are standing at the crossroads. So consider your path. Ask where the old, reliable paths are. Ask where the path is that leads to blessing and follow it. If you do, you will find rest for your souls." But they said, "We will not follow it!"

Yet my people have forgotten me and offered sacrifices to worthless idols! This makes them stumble along in the way they live and leave the old reliable path of their fathers. They have left them to walk in bypaths, in roads that are not smooth and level.
