אַשְׁרֵ֗י שֶׁ֤אֵ֣ל יַעֲקֹ֣ב בְּעֶזְר֑וֹ שִׂ֝בְר֗וֹ עַל־יְהוָ֥ה אֱלֹהָֽיו׃
Berbahagialah orang yang memiliki Allah Yakub sebagai penolongnya, yang menaruh harapannya kepada Yang Mahakekal, Allahnya.
Rashi
Praiseworthy is he in whose help is the God of Jacob, for the Holy One, blessed be He, promised him (Gen. 28:15): “Behold I am with you, and I shall guard You, etc., and I shall return you.” Now why is He praiseworthy? Because He made heaven and earth and the sea, and since all is His, He has the power to guard him on the sea and on dry land; but a mortal king, although he watches him on dry land, cannot watch him on the sea.
Radak
אשרי שאל יעקב בעזרו."Happy is he who has the God of Ya῾aqov for his help": He mentioned Jacob our forefather because he trusted in God, as his brother sought to kill him and he fled from him. Jacob trusted in his heart that God would provide for his needs, even as he went towards him, for God had said to him that He would give him bread to eat and clothes to wear. Similarly, the children of Israel, who trusted in God, were brought out of exile by Him. This repeats the idea using different words.
Ibn Ezra
"Fortunate" - The meaning is that [fortunate is one] that leans on none but God, and does not request help from man.
