Jeremiah 16:2

Thou shall not take thee a wife
Not because it was unlawful; for it was lawful for prophets to marry, and they did; but because it was not advisable, on account of the calamities and distresses which were coming upon the nation; which would be more bearable by him alone, than if he had a wife, which would increase his care, concern, and sorrow. Neither shall thou have sons nor daughters in this place;
in Anathoth, says Kimchi; but it is most likely that Jerusalem in particular is meant, though the whole land of Judea in general may be designed; and though nothing is more desirable than to have children to build up the family, and bear and continue a man's name for futurity, yet in times of public calamity these do but add to the affliction.
