“Aku akan menempuh jalan yang ditempuh semua penghuni bumi. Karena itu, kuatkanlah dirimu dan jadilah laki-laki sejati.

be thou strong therefore, and show thyself a man: This means that your deeds should not be those of an immature youth, but those of a great man.
Tze'enah Ure'enah
“I am going the way of the whole earth, etc.” [2:2]. David said: I am going to die, as is the natural order of all people. You, Solomon, should strengthen yourself and be a man. That is to say, be strong and subdue the evil inclination and do not be childish, like a youth who goes after foolishness.1Radak, I Kings, 2:2.
