The festival so named is first spoken of in Ex. 23:16 as "the feast of harvest," and again in Ex. 34:22 as "the day of the firstfruits" (Num. 28:26). From the sixteenth of the month of Nisan (the second day of the Passover), seven complete weeks, i.e., forty-nine days, were to be reckoned, and this feast was held on the fiftieth day. The manner in which it was to be kept is described in Lev. 23:15-19; Num. 28:27-29. Besides the sacrifices prescribed for the occasion, every o”

Smith's Bible Dictionary “Smith's Bible Dictionary: Pentecost — that is, the fiftieth day (from a Greek word meaning fiftieth), or Harvest Feast, or Feast of Weeks, may be regarded as a supplement to the Passover. It lasted for but one day. From the sixteenth of Nisan seven weeks were reckoned inclusively, and the next or fiftieth day was the day of Pentecost, which fell on the sixth of Sivan (about the end of May).

And while they suppose it proper to honor God, from whom they obtain this plentiful provision, in the first place, they offer the first-fruits of their barley, and that in the manner following: They take a handful of the ears, and dry them, then beat them small, and purge the barley from the bran; they then bring one tenth deal to the altar, to God; and, casting one handful of it upon the fire, they leave the re”

Or "was come", was begun and entered upon; for it was not over, or ended, it being but the third hour of the day, or nine of the clock in the morning, when Peter began his sermon; see Act 2:15. The Vulgate Latin and Syriac versions read, "when the days of Pentecost were fulfilled"; not that there were more days than one, kept at this festival; for though the feasts of passover and tabernacles were observed each of them seven days, according to the law, and eight days according to the Scribes, yet the feast of”

This proclamation was made by the priests with the sound of a trumpet, that the people might observe that this fiftieth day, or day of Pentecost, was devoted to sacred service, and that they were called to holy exercises in it: ye shall do no servile work therein; what was not necessary for food, as Ben Gersom observes, but what was necessary on that account, as kindling a fire, &c. might be done, see Lev 23:7; for this was to be kept in like manner as the first and seven”

The fiftieth day marked the beginning of the Festival of Harvest (the New Testament name of “Pentecost” is derived from the Greek word for “fifty”). For this festival the people were to offer the first portions of the wheat harvest. Each person was also required to take three quarts of fine flour and bake two loaves of yeast bread. These offerings were then presented to the priest officiating at the sanctuary. See also study note on Exod 23:16.”
