Talmud for Pesachim 5:2
אין חוששין שמא גררה חולדה מבית לבית וממקום למקום אם כן מחצר לחצר ומעיר לעיר אין לדבר סוף:
Whilst the R. Yosse and R. Aha were together, the former said to the latter: Does it not seem to you that the passage of this half a mile (twilight) lasts but a second? It is certainly my opinion, said R. Aha. However, R. Hiya does not say so, but each twinkling of an eye, measured by the duration of the passage of half a mile (as R. Nehemiah), is doubtful. R. Mena says : I have made an objection in the presence of R. Aha: Have we not learnt elsewhere, that if an impurity is seen, once during the day and again during the intermediate period, or once in the twilight and again on the morrow, when the certainty exists that the impurity dates partly from this day and partly from the next day, there is a certainty as to the circumstances of the impurity, and the sacrifice is obligatory.

It happened that they decided on a fast at Lydda when it rained before noon. Rebbi Tarphon said to them, go, eat, drink, and make a holiday135Deciding practice following R. Eliezer.. They went, ate, drank, made a holiday, and returned in the evening and recited the Great Hallel. What is the Great Hallel? Give thanks to the supreme Power; truly, His kindness is forever. Give thanks to the Master of masters, 136Ps. 136, the only Hallel recited at night in the synagogue.etc.
