כל הדברים אשר דבר ה' נעשה. The word נעשה, “we will do,” here includes all the commandments of the Lord, negative commandments as well as positive ones, the ones requiring an exertion, an activity. The reason why this is not a misnomer is that if someone refrains from violating a negative commandment he is considered as having “performed” a commandment, i.e the commandment not to violate G’d’s legislation in that matter. We have a complete verse confirming this in Psalms 119,3 אף לא פעלו עולה, בדרכיו הלכו, “they have done no wrong, but have followed His ways.” In other words, not doing evil is considered equivalent to doing good.

ויקח משה את הדם ויזרוק על העם, he sprinkled the blood on them as a symbolic act signifying their entering the covenant with G’d, a covenant that requires blood to seal it. In fact, the blood stain on the garments of the Israelites as a result of this sprinkling was afterwards called עדי [from עד “witness.” Ed.] as it was testimony to the fact that the wearer had become a member of this covenant. This is why after the people had sinned with the golden calf the Torah demands that they remove this sign of such a covenant seeing that they had breached the covenant (Exodus 33,5). The Israelites are also reported to have divested themselves of these blood-stained garments in Exodus 33,6. The reason why G’d had chosen blood to be the symbol of this covenant was to warn the people that if they would prove loyal to the covenant everything would be fine, whereas if they would violate it, G’d on His part would also make the Israelites’ blood something anyone could spill without fear of Divine reprisal.
