1)If a person says כל חמירא וחמיעא וכו׳, and has in mind to be מבטל his חמץ, then מן התורה, it works. 🍞🤷‍♂️💭

‎2)חז״ל instituted בדיקת חמץ, because although you were מבטל your חמץ, you may come to find חמץ on פסח, so on the night before פסח, we do בדיקת חמץ. 🕵️‍♂️🫣🥄🕯️

3)You only make the ברכה when you do בדיקה on the 14th, so if you are going away and did it earlier, you don’t make the ברכה then. But this year we make the ברכה on the 13th, because we can’t do בדיקה on Friday night 🙏1️⃣4️⃣
