Or HaChaim on Deuteronomy 5:25/אור החיים על דברים ה׳:כ״ה

1 היטיבו כל אשר דברו, "they are correct in everything they have said." G'd approved that they accepted Moses as their prophet in the matter and that they agreed to carry out the prophet's instructions. Concerning this undertaking by the Israelites G'd added that He wished the Israelites would maintain their present spiritual high indefinitely. Our sages in Avodah Zarah 5 quote Moses as criticising the people as being ungrateful; they should have seized that moment to ask G'd to convert this wish into something permament and to ensure that they would maintain their lofty spiritual niveau for all times. If the Israelites had done this at that time, subsequent debacles such as that of the spies and the uprising of Korach could all have been avoided.
