1.6.1.17

yadi madhyato yajñasyānuvyāharet | tam prati brūyādaprajā apaśurbhaviṣyasīti prajā vai paśavo madhyaṃ tathā haiva syāt

If any one were to imprecate evil on him in the middle of the sacrifice, let him be thus spoken to, 'Thou shalt be without offspring, without cattle!' for offspring and cattle, indeed, constitute the centre (i.e. the substantial possession of man): and thus it would indeed fare with him.
