וּתְקַעְתִּ֥יו יָתֵ֖ד בְּמָק֣וֹם נֶאֱמָ֑ן וְהָיָ֛ה לְכִסֵּ֥א כָב֖וֹד לְבֵ֥ית אָבִֽיו׃
At ibabaon ko siya na gaya ng tulos sa isang matibay na dako; at siya'y magiging trono ng karangalan para sa sambahayan ng kanyang ama.
Malbim
Providence works in the same way with mankind. A wicked person who is accustomed to pleasures and luxuries would not survive transplantation and so is just taken from the world before his time. Thus, no good comes to the wicked nor does he live very long. However, though a righteous person may be uprooted and transplanted many times over, being dispossessed and suffering physical pain, this is ultimately for his own good, in order to set him in a firm place (Isaiah 22:23). For he will yet bring forth fruit in old age; (Psalms 92:15) For he will yet bring forth fruit in old age; (Psalms 92:15) and the Lord's purpose prospering in his hand (Isaiah 53:10). (Ch.8:11-20).
Rashbam
נאמן הוא, a permanent presence, belonging to the foundation at any time of the day. The word נאמן occurs in this sense of Isaiah 22,23 יתד במקום נאמן, “as a peg in a firm place.” It is something that is not apt to fall down.
Rashi
a peg יָתֵד, like (Isa. 22:23): “And I will thrust him like a peg (יָתֵד) in a sure place.”
