In the fifth aliyah of Parshas Bo, we see the first part of the transition of the Jewish People from slavery to servitude of Hashem. When Moshe commands the elders of Bnei Yisroel to bring the korban pesach , he says mishchu u'kichu , if you have a sheep take it, and if you don’t have a sheep buy one. On a deeper level, we can understand this to mean mishchu , remove yourself from the servitude of Pharoh, u’kichu , and take for yourself servitude to Hashem. We have 613 mitzvos , 613 ways of serving Hashem as part of the fabric of our lives. We don't stop our day to perform mitzvos , the obligations that we have are the way we live. - Library: Bnai Jacob Shaarei Zion - RabbiHauer.org
