In the wake of horrific attacks by Palestinian terrorists that left hundreds of Jews dead, Rabbi Pesach Wolicki called on all friends of Israel to join in prayer. He recommended Psalm 20:

1For the leader. A psalm of David.
la-menat-TSE-akh, miz-MOR, l’-da-VID
אלַמְנַצֵּ֗חַ מִזְמ֥וֹר לְדָוִֽד׃
2May Hashem answer you in time of trouble, the name of Yaakov‘s Hashem keep you safe.

3May He send you help from the sanctuary, and sustain you from Tzion.
yish-LAKH-ez’-RE-kha mi-ko-DESH u-mi-TZI-yon yis-a-DE-kha
גיִשְׁלַֽח־עֶזְרְךָ֥ מִקֹּ֑דֶשׁ וּ֝מִצִּיּ֗וֹן יִסְעָדֶֽךָּ׃
4May He receive the tokens of all your meal offerings, and approve your burn offerings. Selah.

5May He grant you your desire, and fulfill your every plan.
YIT-ten l’-KHA kheel-va-VE-kha v’-kol a-tza-t’-KHA ye-ma-LAY
היִֽתֶּן־לְךָ֥ כִלְבָבֶ֑ךָ וְֽכׇל־עֲצָתְךָ֥ יְמַלֵּֽא׃
6May we shout for joy in your victory, arrayed by standards in the name of our God. May Hashem fulfill your every wish.

7Now I know that Hashem will give victory to His anointed, will answer him from His heavenly sanctuary with the mighty victories of His right arm.

8They [call] on chariots, they [call] on horses, but we call on the name of Hashem our God.

10Hashem, grant victory! May the King answer us when we call.
