'Highway' in the Bible

‘Yet My people have forgotten Me;They burn incense to worthless gods,They have stumbled from their waysFrom the ancient roads,To walk in pathways,Not on a highway,

“Place for yourself road signs [toward Canaan],Make for yourself guideposts;Turn your thought and attention to the highway,To the way by which you went [into exile].Retrace your steps, O virgin of Israel,Return to these your cities.
