B'SHAYI P'HI (Sh'H P'H) On all sorts of excuses/ on various pretexts/ vain pretext , Why do you come to bother me, it's Sabbaath today, it's Pessah today… / to delay things
Figuratively: with empty excuses; with evasive talk to avoid carrying out a task (source: based on Rashi’s interpretation of the acronym formed from “Shabbat today, Passover today,” days on which work is forbidden).
("And the laws of the king they do not keep" (Esther 3) – meaning they exempt for the whole year (that is, throughout the year) by 'B'SHAYI P'HI' – Rashi: meaning they exempt for the year with 'B'SHAYI P'HI' – 'It is Shabbat today, it is Passover today,' and we are forbidden to perform work" – Rashi, Megillah 13b, and also: "The Antokolusians and Israelites exempted their people with 'B'SHAYI P'HI': they carelessly discarded before him, and once in the jubilee, miserable scraps of creation, a work done between the suns... as if truly 'the Hebrew subject' is the main point here" – Bialik / A.L. Pestrenk)
