What do tillage (harth) and stock (nasl) mean?

Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. "Tillage" refers to crops, and "stock" refers to all types of animal offspring. [Ibn ʿAbbās, ʿIkrimah, and others]
2. Al-Zajjāj reported that some people said "tillage" refers to women, and "stock" refers to children. He noted that this interpretation is reasonable because a woman is sometimes referred to as "tillage" (harth). (See 2:223)
