'Forefathers' in the Bible

God, having spoken in former times in fragmentary and varied fashion to our forefathers by the prophets,

do not harden your hearts as your forefathers did in the time of the provocation on the day of the temptation in the Desert,

where your forefathers so sorely tried My patience and saw all that I did during forty years.

seeing that the warning still comes to us, "To-day, if you hear His voice, do not harden your hearts as your forefathers did in the time of the provocation."

Not like the covenant that I made with their fathersOn the day when I took them by the handTo lead them out of the land of Egypt;For they did not abide in My covenant,And so I withdrew My favor and disregarded them, says the Lord.
