פּירוש אויף תהילים 145:14

supports (The “nun” is missing from the “aleph-beth” because David saw in it a serious downfall [Amos 5:2]: “The virgin of Israel has fallen and shall not continue to rise.” And he returned and supported her with the holy spirit: The Lord supports all those who fall.)

The Lord upholds all that fall (סומך ה' לכל הנופלים): The Lord supports all those who fall, and the bowed down, who are the poor and oppressed, He raises up with His compassion.
