ישעיהו כב:כד פירוש: רש״י ואבן עזרא

the children and the grandchildren (צֶאֱצָאִים וּצְפִיעוֹת). Jonathan renders: the children and the children’s children. Menachem (Machbereth p. 151) associates it with, (Ezekiel 4:15) “Cattle dung (צְפִיעֵי).” This teaches us that it is an expression of tiny infants that issue forth from their mother’s womb. making צְפִיעוֹת an expression of coming out, i.e., a thing that comes out.

And they shall hang, etc. Having compared Eliakim with a nail, the prophet continues, they shall hang upon it, etc.

all the small vessels the smallest of their families shall take pride in him and rely on him.
