Ana Avda d'Kudasha Brikh Hu is Aramaic for "I am a servant of Hashem." It comes from the the Brikh Shmay prayer that we recite when removing the Torah scroll from the ark on days that we read from the Torah.
Nissan is a happy month, so we're going to have some fun today on the Beams. Take a break from Passover cleaning and watch Dovid Gabay sing his animated version of Ana Avda. Your children will love this!
