יְקַבֵּל צְלוֹתָךְ יְיָ בְּיוֹמָא דְעָקָא יְשַׂגְבִינָךְ שְׁמָא דֶאֱלָהָא דְיַעֲקֹב.
1. answer you | יַעַנְךָ – The identity of the "you" to whom these words are addressed is debated. See the note on the previous verse that according to Rashi the speaker of the psalm is David, who addresses his general Yoav in the second person. According to Malbim, in contrast, the speaker of the psalm is the nation who addresses their king, David. He suggests that the psalm relates to the war against the Philistines described in Shemuel II 22, where David found himself endangered. When word got back to Jerusalem of his dire straits, the people prayed that Hashem answer his cries for help.
2. name | שֵׁם – See Sforno that even the very name of God can protect one, since having a reputation that one is part of God's nation and that "His name is upon you" (see Devarim 28:10), instills fear in the enemy.
3. Yaakov | יַעֲקֹב – Here, as in many poetic passages, the name Yaakov might not refer to the forefather, but to the nation as a whole. See Tehillim 14:7, 53:7, 78:5, and 105:10 where the names Yaakov and Yisrael are parallel, with both terms referring to the nation. Cf. Midrash Tehillim and many commentators that Yaakov is specified as he underwent more troubles than the other patriarchs. Our verse, in fact, echoes Yaakov's words when thanking Hashem for caring for him in such times: "לָאֵל הָעֹנֶה אֹתִי בְּיוֹם צָרָתִי" (to the God who answered me on the day of my distress).
4. secure you | יְשַׂגֶּבְךָ – See Radak and Hoil Moshe. The root "שגב" more literally means "to be high", but often takes the connotation of being "safely set on high", with the related noun "מִשְׂגָּב" (a secure height or stronghold) often being paired with words such as "מִבְצַר" and "מְצוּדָה" (fortress) or "מִפְלָט" (a place of escape). Alternatively, the word might mean: "exalt you", with the connotation perhaps being that when victory comes, you will be elevated and glorified.
