And Samuel said to Saul: Thou hast done foolishly, and hast not kept the commandments of the Lord thy God, which he commanded thee. And if thou hadst not done thus, the Lord would now have established thy kingdom over Israel for ever.

And Samuel saith unto Saul, 'Thou hast been foolish; thou hast not kept the command of Jehovah thy God, which He commanded thee, for now had Jehovah established thy kingdom over Israel unto the age;

And Samuel said to Saul, You have done a foolish thing: you have not kept the rules which the Lord your God gave you; it was the purpose of the Lord to make your authority over Israel safe for ever.

And Samuel said to Saul: "You have acted foolishly. You have not kept the commandments of the Lord your God, which he instructed to you. And if you had not acted in this way, the Lord would, here and now, have prepared your kingdom over Israel forever.

Thou hast done foolishly - Motives of worldly expediency were not to be weighed against the express commandment of God. All the circumstances and all the dangers were as well known to God as they were to Saul, and God had bidden him wait until Samuel came. Here was exactly the same sin of willful disobedience which broke out again, and was so severely reproved 1-Samuel 15:17-23.

And Samuel said to Saul, Thou hast done foolishly: thou hast not kept the commandment of the LORD thy (i) God, which he commanded thee: for now would the LORD have established thy kingdom upon Israel for ever.
(i) Who willed you to obey him, and rest on the words spoken by his prophet.

And Samuel said to Saul, thou hast done foolishly,.... Not by intruding himself into the priest's office, with that he is not charged, but not waiting the full time till Samuel came; which showed his impatience, disregard to Samuel, and distrust of God; and though he thought he had acted wisely, and taken the proper precautions in his circumstances, yet he acted foolishly; and though a king, Samuel being a prophet of the Lord, and in his name, spared not to tell him so:
thou hast not kept the commandment of the Lord thy God, which he commanded thee; by his prophet, that he should wait seven days for his coming, who would then offer sacrifices, and tell him what he should do; and not to keep the commandment of God was acting a foolish part:
for now would the Lord have established thy kingdom upon Israel for ever; that is, for a long time, on his son, and son's son; and then, according to promise and prophecy, it would come to one of the tribe of Judah; but now seeing he had acted such a part, it should not continue long in his family, no longer than his own life, and quickly come into other hands.

For ever - The phrase, for ever, in scripture often signifies only a long time. So this had been abundantly verified, if the kingdom had been enjoyed by Saul, and by his son, and by his son's son; after whom the kingdom might have come to Judah.
