Acts 3:13 No, God did it! He is the God of Abraham, the God of Isaac, and the God of Jacob. He is the God of all our fathers. He gave glory to Jesus, his special servant. But you handed him over to be killed. Pilate decided to let him go free. But you told Pilate you did not want him.
Mark 12:26 Surely you have read what God said about people rising from death. In the book where Moses wrote about the burning bush, it says that God told Moses this: ‘I am the God of Abraham, the God of Isaac, and the God of Jacob.’
The real question today is, what our Jewish Brothern are depending on for Salvation.

The usual rendering in the English versions for the Hebrew words , , derivatives of the stem , which in the verb occurs only in the "nif'al" and "hif'il" forms. Other Hebrew terms translated by the corresponding forms of the English "save" and its synonyms are: (1) . This word, meaning in the "ḳal" "to live," acquires in the "pi'el" and "hif'il" the signification "to keep alive," "to save alive" (Gen. xii. 12, xix. 19, xlv. 7; Ex. i. 17, 18: Num. xxii. 33; I Sam. xxvii. 11). Ezekiel employs it to express the condition of the repentant sinner who, having escaped the penalty of sin (death), continues safe in life. (2) = "to deliver" (II Sam. xix. 9; A. V. "save "). (3) , in the "pi'el" (I Sam. xix. 11; II Sam. xix. 5; Job xx. 20). (4) = "to keep," "to spare" (Job ii. 6). (5) = "to redeem" (see Go'el). (6) = "to release."
Hosanna.
The underlying idea of all these words, save the last two, is help extended and made effective in times of need and danger, and protection from evil. "Padah" means "to free by paying ransom." "Ga'al" denotes the assumption of an obligation incumbent originally on another or in favor of another. "Yasha'" primitively means "to be or make wide." Evil and danger are always regarded as narrowing conditions or effects. From the "narrow" place the sufferer cries out. When help has come he is in a "wide" place (Ps. cxviii. 5). In battle enemies beset, surround, hem in (ib. verses 10, 11). Success in the combat relieves and removes the pressure. Hence "yasha'" and its derivatives express "victory." This is the import of the Hebrew in such passageś as Judges xv. 12; I Sam. ii. 1, xiv. 45; II Sam. xxii. 51; and Isa. xlix. 8. Combined with "rinnah," the word "yeshu'ah" signifies the jubilant cry of the victors (Ps. cxviii. 15). The passionate appeal "Hoshi'ah-nna" (ib. verse 25; = "Hosanna") ought to be rendered "Give victory," a translation all the more assured by the certainty that the psalm is Maccabean. He who leads to victory in battle, therefore, is the "moshia'" = "savior" (e.g., Othniel, in Judges iii. 9; Ehud, ib. iii. 15; Gideon, ib. vi. 36, 37; and the verb in Judges vii. 3; I Sam. xxv. 26; Ps. xliv. 4; Job xxvi. 2). But, according to the ancient concept, God Himself is the leader in battle ("Ish Milḥainah"; Ex. xv. 3). This throws light on the original bearing of the terms "savior" and "salvation" when applied to the Deity (comp. Isa. xxv. 9, xlv. 20). Language has preserved this notion in the epithet "Elohe yish'enu," which, idiomatically construed, means "our victorious God" (I Chron. xvi. 35; Ps. lxxix. 9; "thy victorious God," Isa. xvii. 10; comp. the similar construction "magen yish'aka" = "thy victorious shield," II Sam. xxii. 36; in the first three passages the A. V. has "God of our salvation" or "God of thy salvation"). Perhaps the king as the head of the army was greeted with the salutation "Hoshi'ah" = "Hosanna," corresponding to (II Kings x. 19; Neh. ii. 3). This would appear from II Kings vi. 26, the woman's apostrophe carrying with it all the greater irony if it repeated the usual greeting of respect, and the king's answer being, like that of Naomi (Ruth i. 20, 21), a clever turn of the terminology of the address. This would explain also the greeting extended to Jesus (see Hosanna) and the Messianic construction of the psalm. He was hailed thereby as "the king."
From this idea of "victory," those of help in trouble and rescue from evil are logical derivatives; but it is not impossible that even in this secondary usage of the term "salvation" the primary notion of a successful combat is operative. Evils are caused by demons: victory over them results in escape, a grateful help. Thus man is saved from trouble (Ps. xxxiv. 7, Hebr.; Isa. xxxiii. 2; Jer. xiv. 8, xxx. 7), from enemies (I Sam. iv. 3, vii. 8), from violence ("lion," Ps. xxii. 22; "men of blood,"ib. lix. 3, Hebr.), from reproach (ib. lvii. 4 [A. V. 3]), from death (ib. vi. 5, 6), from a great calamity (Jer. xxx. 7), from sin, by paying the ransom ("yifdeh"; Ps. cxxx. 8), and from uncleanness (Ezek. xxxvi. 29).
