who would rule purified Israel as Yahweh's representative at the end of time—a messiah. The first to mention this were Haggai and Zechariah, both prophets of the early Persian period. They saw the messiah in Zerubbabel, a descendant of the House of David who seemed, briefly, to be about to re-establish the ancient royal line, or in Zerubbabel and the first High Priest, Joshua (Zechariah writes of two messiahs, one royal and the other priestly). These early hopes were dashed (Zerubabbel disappeared from the historical record, although the High Priests continued to be descended from Joshua), and thereafter there are merely general references to a Messiah of David (i.e. a descendant). From these ideas, Second Temple Judaism would later emerge, whence Christianity, Rabbinic Judaism, and Islam. Worship Festivals and sacrifice The centre of Yahweh's worship lay in three great annual festivals coinciding with major events in rural life: Passover with the birthing of lambs, Shavuot with the cereal harvest, and Sukkot with the fruit harvest. These probably pre-dated the arrival of the Yahweh religion, but they became linked to events in the national mythos of Israel: Passover with the exodus from Egypt, Shavuot with the law-giving at Mount Sinai, and Sukkot with the wilderness wanderings. The festivals thus celebrated Yahweh's salvation of Israel and Israel's status as his holy people, although the earlier agricultural meaning was not entirely lost. His worship presumably involved sacrifice, but many scholars have concluded that the rituals detailed in Leviticus 1–16, with their stress on purity and atonement, were introduced only after the Babylonian exile, and that in reality any head of a family was able to offer sacrifice as occasion demanded. A number of scholars have also drawn the conclusion that infant sacrifice, whether to the underworld deity Molech or to Yahweh himself, was a part of Israelite/Judahite religion until the reforms of King Josiah in the late 7th century BCE. Sacrifice was presumably complemented by the singing or recital of psalms, but again the details are scant. Prayer played little role in official worship. Temples The Hebrew Bible gives the impression that the Jerusalem temple was always meant to be the central or even sole temple of Yahweh, but this was not the case. The earliest known Israelite place of worship is a 12th-century BCE open-air altar in the hills of Samaria featuring a bronze bull reminiscent of Canaanite Bull-El (El in the
