Psalms 41:4 “יְהוָה–יִסְעָדֶנּוּ, עַל-עֶרֶשׂ דְּוָי”
“YHVH support him upon the bed of illness”
The sages tell us that a person who visits the sick in his bed should not sit by his legs because the Shechina is by the head and the angel of death is by the feet.
If a person is righteous, then YHVH is by his head and the Shechina surrounds his body up to the feet. For Jacob it was said Genesis 49:33 “וַיְכַל יַעֲקֹב לְצַוֹּת אֶת-בָּנָיו, וַיֶּאֱסֹף רַגְלָיו אֶל-הַמִּטָּה; וַיִּגְוַע, וַיֵּאָסֶף אֶל-עַמָּיו ”
“And when Jacob made an end of charging his sons, he gathered up his feet into the bed, and expired, and was gathered unto his people. ”
The bed is the aspect of the Shechina and when Jacob finished giving the blessings to his children, he raised his feet to the bed that is the aspect of the Shechina and his soul ascended to its place above.
Impure people have the angel of death surrounding their body from all directions with his sword waiting for the exact moment to separate the soul from the body.
“וְאַחֲרִיתָהּ, מָרָה כַלַּעֲנָה; חַדָּה, כְּחֶרֶב פִּיּוֹת ”
“But her end is bitter as wormwood, sharp as a two-edged sword.”
Jacob was the first to be sick in the Torah. The sages told us that Jacob asked God to give him the opportunity to bless his son before leaving the world. We know that the passing day of a righteous person is when his energy and the light from all of his spiritual work are fully revealed. Jacob knew that the entire future of the correction process depended on the blessings of the twelve sons.
Before Jacob change the system, death was a sudden event. When the time of death comes, a person would sneeze and his soul would leave the body. This is the reason why people bless each other for health when they hear a sneeze.
Don’t get upset with Jacob because he did what’s best for us. Sickness is an aspect of Mercy that allows us time to correct the soul before it leaves this world. Many people suffer greatly before they die and that is their opportunity to repent and/or pay the last payments on the correction process.
