ציטירנדיקער פּירוש אויף דברים 6:6

It also wanted [to teach], by way of the [Sages], may their memory be blessed, saying (Berakhot 6b), "Whoever has awe of the Heavens, his words will be heard;" and the reason [for this] is that the one who fears God will speak from the depths of his soul, and since that is the case, the soul of the listener will recognize [that] and accept the rebuking chastisement; but if the words came from the body, there is no resonance for the soul to listen to them, as the rabbis, of blessed memory, have hinted about what the verse stated (Deuteronomy 6:6), "And these words shall be etc. upon your heart" [and] then "and you shall review them with your children," which are the students. And this is what it said, "Bereishit," which is awe - as they, of blessed memory, have said - "God created the heavens," the explanation [of which] is that one should have awe of the Heavens, [and] then they will listen to his voice and 'he will teach knowledge to people' and that is what it states, "and the earth."

ולא דקדק באותיותיה – To emit them with one’s lips clearly – so that two words where the first letter of the second word begins with the same letter that concluded the first word – such as “Al L’va’vekha” (Deuteronomy 6:6 – “Take to heart”) עשב בשדך” (Deuteronomy 11:15 – “I will provide grass in the fields”), ועבדתם מהרה"” (Deuteronomy 11:17 – “and you will soon perish”) - that if you do not place a space between [these words] to separate them, you will end up reading these two (identicaletters as one letter.

לא יצא – As it is written (Deuteronomy 6:6), “these instructions [which I charge you this day],” as they are, that is to say, as they are organized in the Torah. But however, if one first read the "ויאמר" passage (Numbers 15:37-41) prior to the והיה אם שמוע"” passage (Deuteronomy 11:13-21), or the “והיה אם שמוע” passage prior to “שמע” (Deuteronomy 6:4-9), it would appear that it is not important read out of order, and one fulfills [one’s obligation] since they are not set up that way, one after the other in the Torah.
