² sn The doubling of the time after the birth of a female child is puzzling (see the remarks in J. Milgrom, Leviticus [AB], 1:750-51; and G. J. Wenham, Leviticus [NICOT], 188). Some have argued, for example, that it derives from the relative status of the sexes, or a supposed longer blood flow for the birth of a woman, or even to compensate for the future menstrual periods of the female just born. Perhaps there is a better explanation. First, a male child must be circumcised on the eighth day, so the impurity of the mother could not last beyond the first seven days lest it interfere with the circumcision rite. A female child, of course, was not circumcised, so the impurity of the mother would not interfere and the length of the impure time could be extended further. Second, it would be natural to expect that the increased severity of the blood flow after childbirth, as compared to that of a woman’s menstrual period, would call for a longer period of impurity than the normal seven days of the menstrual period impurity (compare Lev 15:19 with 15:25-30). Third, this suggests that the fourteen day impurity period for the female child would have been more appropriate, and the impurity period for the birth of a male child had to be shortened. Fourth, not only the principle of multiples of seven but also multiples of forty applies to this reckoning. Since the woman’s blood discharge after bearing a child continues for more than seven days, her discharge keeps her from contact with sacred things for a longer period of time in order to avoid contaminating the tabernacle (note Lev 15:31). This ended up totaling forty days for the birth of a male child (seven plus thirty-three) and a corresponding doubling of the second set of days for the woman (fourteen plus sixty-six). See R. E. Averbeck, NIDOTTE 2:368-70. The fact that the offerings were the same for either a male or a female infant (vv. 6-8) suggests that the other differences in the regulations are not due to the notion that a male child had greater intrinsic value than a female child (J. E. Hartley, Leviticus [WBC], 169).

⁶ sn This refers to a well-known earthquake that occurred during the first half of the 8th century b.c. According to a generally accepted dating system, Uzziah was a co-regent with his father Amaziah from 792-767 b.c. and ruled independently from 767-740 b.c. Jeroboam II was a co-regent with his father Joash from 793-782 b.c. and ruled independently from 782-753 b.c. Since only Uzziah and Jeroboam are mentioned in the introduction it is likely that Amos’ mission to Israel and the earthquake which followed occurred between 767-753 b.c. The introduction validates the genuine character of Amos’ prophetic ministry in at least two ways: (1) Amos was not a native Israelite or a prophet by trade. Rather he was a herdsman in Tekoa, located in Judah. His mere presence in the northern kingdom as a prophet was evidence that he had been called by God (see 7:14-15). (2) The mighty earthquake shortly after Amos’ ministry would have been interpreted as an omen or signal of approaching judgment. The clearest references to an earthquake are 1:1 and 9:1, 5. It is possible that the verb הָפַךְ (hafakh, “overturn”) at 3:13-15, 4:11, 6:11, and 8:8 also refers to an earthquake, as might the descriptions at 2:13 and 6:9-10. Evidence of a powerful earthquake has been correlated with a destruction layer at Hazor and other sites. Its lasting impact is evident by its mention in Zech 14:5 and 2 Chr 26:16-21. Earthquake imagery appears in later prophets as well (cf. D. N. Freedman and A. Welch, “Amos’s Earthquake and Israelite Prophecy,” Scripture and Other Artifacts, 188-98). On the other hand, some of these verses in Amos could allude to the devastation that would be caused by the imminent military invasion.
