Jeremiah 31:21

Set thee up waymarks, make thee high heaps: set thine heart toward the highway, [even] the way [which] thou wentest: turn again, O virgin of Israel, turn again to these thy cities.

Ver. 21. Set thee up waymarks.] Statue tibi statuas Mercuriales - q.d., I will surely bring thee back by the same way thou wentest hence into captivity; therefore take good notice of the way now, that thou mayest know it again another time. This God saith to quicken their faith, and to ascertain them of his love and favour; which is not like the winter sun, which casteth a goodly countenance when it shineth, but giveth little heat and comfort, &c. We must also set up waymarks, observe how we fell from the Lord, repent and do our first works.

Set thine heart towards the highway.] This is done, saith Augustine, when God is sought for God's sake. Sed vix diligitur Iesus propter Iesum, saith the same Father; but this is rarely done.
