Answer Amen After Every Brachah

“השנים לשלש התבואה את ועשת הששית בשנה לכם ברכתי את וציויתי” (כא כה)

Harav Yaakov Chaim, the only son and successor of the Ben Ish Chai, wrote: The word לכם [with the kollel] is numerically equivalent to אמן. So we can explain the passuk as follows: “Vetzivisi, es birchasi lachem” – HaKadosh Baruch Hu instructs you that whenever you hear a brachah answer amen to it. As the Rambam rules (Brachos 1 73): “Anyone who hears someone in Am Yisrael making a brachah, any brachah, even if he did not hear the entire brachah from beginning to end, and even though he is not obligated in that brachah, is obligated to answer amen.”
