After Moshe spoke to Paroh, Paroh decreed that the Yidden would have to gather straw themselves in order to make bricks. It is interesting that: ןֶבֶתּ straw and: ַקשׁ stalks which symbolize a flammable and weak substance, turns into: ְל ֵב ִנ יםi.e., tough, hard bricks. Similarly, the filthy dirty earth is the basis of the most beautiful and sweet fruits & flowers and all kinds of growing things. Mr. Nobody zero turns into the most important and glorious person. Hashem made His world with this concept, and perhaps when the Yidden were manufacturing bricks from ַק שׁ stalks, they were being given a Remez for their future Yeshua.
Such slaves of lowly Egyptians (who are called: םָח יֵנְבּ תַמְדַא תיברע תלפתב הנומאו תמא of the land of Cham, which emphasizes their lowliness) suddenly become: תוֹאְבִצ 'ה tough army men. The world of Torah is full of opportunities to convert the lowest to the highest, like: םוֹקָמְבּ ןיִלוֹכְי םיִרוּמְג םיִקיִדַצ ןיֵא םיִדְמוֹע הָבוּשְׁתּ יֵלֲﬠַבֶּשׁ דוֹמֲﬠַל ברכות לד ב Baalei Teshuva are even GREATER than pure Tzaddikim.
Chazal say that when the body of Shaul HaMelech was dug up, they found it to be whole. It is known that the reason why a dead body decomposes is because of the Midda of jealousy. Like Shlomo HaMelech said: תוֹמָצֲﬠ בַקְרוּ הָאְנִק משלי יד ל a person’s bones decay because of Kin'ah, and big Tzaddikim who were known for Ayin Tova were whole even many years after their death, like R' Shraga Feivel Mendelovitz Zatzal and R' Moshe Yom Tov Wachtfogel Zatzal (father of R' Nosson Zatzal).
The stories of Shaul and Dovid are loaded with Shaul’s unending Kin'ah of Dovid So why was his body Davka whole after he was Niftar? [Of course, we have no understanding of these great giants, but the Torah tell us these things so we can take a lesson.]
