"The murmurings of ancient Israel and their rebellious discontent, as well as the mighty miracles wrought in their favor and the punishment of their idolatry and ingratitude, are recorded for our benefit. The example of ancient Israel is given as a warning to the people of God, that they may avoid unbelief and escape His wrath. If the iniquities of the Hebrews had been omitted from the Sacred Record, and only their virtues recounted, their history would fail to teach us the lesson that it does. 4T 11.1"
"Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come."
Both passages explicitly state that the experiences of the Israelites were recorded as examples and warnings for future generations. The EGW passage directly echoes the sentiment and purpose outlined in 1 Corinthians 10:11.
