Isru Ḥag


ISRU ḤAG (Heb. אִסְרוּ חַג), designation for the day following the three *pilgrim festivals. The name is derived from Psalms 118:27: "Bind the sacrifice (isru hag) with cords, even unto the horns of the altar," which the Talmud (Suk. 45b) interprets: "He who makes an addition (issur) to the festival (ḥag) is considered to have built an altar and sacrificed on it." Rashi comments that this is understood by some to refer to the day after a festival. In the Jerusalem Talmud the day is known as bereih de-mo'ada ("the son of the festival"; tj, Av. Zar. 1:1, 39b). Liturgically, it has been the custom to treat isru ḥag as a sort of minor holiday; no supplicatory and penitential prayers are said, and fasting and funeral eulogies are prohibited.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
