Leviticus 23:16

השבת השביעת — Translate this as the Targum does שבועתא שביעתא THE SEVENTH WEEK. עד ממחרת השבת השביעת תספרו EVEN UNTIL THE MORROW AFTER THE SEVENTH WEEK SHALL YE NUMBER — until, but not including the day until which you count: thus there are 49 days (the seven complete weeks spoken of in the preceding verse). 'חמשים יום והקרבתם מנחה חדשה לה‎… FIFTY DAYS — AND YE SHALL OFFER A NEW OBLATION UNTO THE LORD — i. e. on the fiftieth day ye shall offer it. This, I say, is a Midrashic explanation, but the literal sense is: “Even unto the morrow of the seventh week which is the fiftieth day shall ye number”: the text has its phrases inverted. מנחה חדשה A NEW MEAL OFFERING — It was the first meal-offering that was offered from the new crop. And if you ask, “But surely the meal-offering of the Omer has already been offered on the 16th of Nisan”?! Then I reply: It (the Omer) was not like all the other meal-offerings — which, with one exception (cf. Numbers 5:15), were all brought of wheat — since it was brought of barley and therefore it is not taken into account (cf. Menachot 84b).

to the morrow after the seventh sabbath shall you number fifty days and you shall offer a new meal offering to the Lord.
