And worthy is he who unites Them in ‘the recitation of the Shm’a’, in fear and love. For when Israel strives, in the Written Torah and in the Oral Torah, in love and fear, it is stated of them: Do not take the mother upon the children. (Deut. 22:6)
But when they are not striving in them, in love and fear, it is stated of them: You shall surely send away the mother... (Deut. 22:7)
When Israel keeps the Sabbath, with Remember and Observe, in fear and love, it is stated of them: (Deut. 22:6) Do not take the mother upon the children... And if not, it is written of them: (Deut. 22:7) You shall surely send away... etc. – two dismissals.
