Sanhedrin 97b
It has been taught; R. Nathan said: This verse pierces and descends to the very abyss:
11 For the vision is yet for an appointed time, but at the end it shall speak, and not lie: though he tarry, wait for him; because it will surely come, it will not tarry.
12 Not as our Masters, who interpreted the verse, until a time and times and the dividing of time;13 nor as R. Simlai who expounded, Thou feedest them with the bread of tears; and givest them tears to drink a third time;
14 nor as R. Akiba who expounded, Yet once, it is a little while, and I will shake the heavens, and the earth:
15 but the first dynasty [sc. the Hasmonean] shall last seventy years, the second [the Herodian], fifty two, and the reign of Bar Koziba
16 two and a half years.

What is meant by 'but at the end it shall speak [we-yafeah] and not lie?'
— R. Samuel b. Nahmani said in the name of R. Jonathan: Blasted be18 the bones of those who calculate the end.19 For they would say, since the predetermined time has arrived, and yet he has not come, he will never come. But [even so], wait for him, as it is written, Though he tarry, wait for him. Should you say, We look forward [to his coming] but He does not: therefore Scripture saith, And therefore will the Lord wait, that he may be gracious unto you, and therefore will he be exalted, that he may have mercy upon you.
20 But since we look forward to it, and He does likewise, what delays [his coming]? — The Attribute of Justice delays it.
21 But since the Attribute of Justice delays it, why do we await it? — To be rewarded [for hoping], as it is written, blessed are all they that wait for him.
