E quando repousava, ele dizia: "Volta, ó Eterno, às miríades de milhares de Yisra'el." {פ}

If one understands the deeper meaning of this commandment, one also gains an insight into the mysteries of Creation. We find a statement by Rabbi Eliezer in Yevamot 63 that anyone who neglects to fulfill the commandment to be fruitful is considered as having the sin of spilling innocent blood on his hands, the reason being that the Torah says in Genesis 9,6: "Whoever sheds the blood of man, by man shall his blood be shed." Since the Torah goes on to say : "Be fertile, increase, etc.," it is clear that failure to do so is considered a mortal sin. Rabbi Yaakov says: "Failure to try and have issue is a way of diminishing G–d's image in this world, since the Torah (still in verse 6 of this chapter) adds: 'For in His image did G–d make man.' Immediately afterwards follows the commandment to be fruitful." The Rabbis taught in Yevamot 64 that Numbers 10,36 ובנחה יאמר: שובה ה' רבבות אלפי ישראל, "When the ark came to rest, Moses would say 'return O Lord, You who are Israel's myriads of thousands,'" teaches that G–d's Presence is not found when Israel numbers fewer than 22000 souls." If Israel would number 21999 at any time and one of those Israelites failed to perform the מצוה of פרו ורבו, that person would be responsible for preventing the whole people from enjoying the Presence of the שכינה in their midst. We have now had three separate statements on the seriousness of failing to comply with the commandment to be fruitful. A) Failure to try and reproduce is equivalent to committing bloodshed; B) Failure to try and produce issue diminishes G–d's image in the world; C) Failure to fulfil this injunction prevents Israel from enjoying the Divine Presence in its midst. Prior to the statement quoted in the name of Rabbi Eliezer, the same Rabbi Eliezer is on record saying that a person who fails to marry is not an אדם, seeing that the Torah says of man (אדם) that "G–d created him male and female. He called their name Adam." (Genesis 5,2). You should appreciate that the statement of Rabbi Eliezer is to be understood as a general rule, whereas the subsequent statements are פרטים details, i.e. applications of the כלל. We must first understand Rabbi Eliezer.

The reason that men of military age who are engaged in building a house for themselves, or in the planting of a vineyard which has not yet borne fruit, or who have betrothed a bride without as yet having consummated the marriage are free to return to their homes to complete these endeavours is explained by the Rekanati. We are quoting verbatim: "Know that the three categories of people listed by the Torah in 20,5-8 are people who are especially prone to meet with disaster. The attribute of Justice is more likely to seek them out than others. We have proof for this from what happened during the episode of the golden calf. If you will examine the various occasions when the Torah reports the Jewish people as sinning while they were in the desert, you will find that it was almost invariably after they had experienced a spiritual "high." The first set of tablets were smashed because of the golden calf. Our sages explain that the עין הרע the evil eye, had focused on these tablets. After the Israelites had travelled only three days' journey from Mount Sinai, the very next verse (Numbers 10,36) ויהי העם כמתאוננים, רע באזני השם "The people were complaining before the Lord; they spoke evil within the hearing of G–d." All this in spite of the Torah having told us that the Presence of G–d rested over their encampment. The sin of the spies occurred at a time when the people were ready to conquer ארץ ישראל, i.e. they were at a spiritual "high." The sin of בעל פעור occurred immediately after G–d had made Bileam bless the people instead of cursing them as he had been hired to do (Cf. Numbers chapters 24 and 25). After all, Michah 6,5 reminds the Jewish people to remember the advice given to Bileam by Balak how to curse the Jewish people and how Bileam had responded to him. In that admonition of the prophet the Jewish people are addressed by G–d as "My people," i.e. they were on a morally high level at that time. This is the meaning of the statement of our sages in Shabbat 130 that ליכא כתובה דלא רמו בה תיגרא, "There is no marriage contract which does not give rise to some dispute." Thus far the Rekanati.
