And the people came up out of Jordan on the tenth day of the first month, and encamped in Gilgal, in the east border of Jericho. And those twelve stones, which they took out of Jordan, did Joshua pitch in Gilgal. And he spake unto the children of Israel, saying, “When your children shall ask their fathers in time to come, saying, ‘What mean these stones?’ Then ye shall let your children know, saying, ‘Israel came over this Jordan on dry land’; for the LORD your God dried up the waters of Jordan from before you, until ye were passed over, as the LORD your God did to the Red sea, which He dried up from before us, until we were gone over: that all the people of the earth might know the hand of the LORD, that it is mighty: that ye might fear the LORD your God for ever.”
Joshua 4:19-24
Thou hast proved mine heart; thou hast visited me in the night; thou hast tried me, and shalt find nothing; I am purposed that my mouth shall not transgress.
Psalm 17:3
My son, attend to my words; incline thine ear unto my sayings. Let them not depart from thine eyes; keep them in the midst of thine heart. For they are life unto those that find them, and health to all their flesh.
Proverbs 4:20-22
