Chapter 121

1A song for ascents. I shall raise my eyes to the mountains, from where will my help come?   אשִׁ֗יר לַֽמַּֽ֫עֲל֥וֹת אֶשָּׂ֣א עֵ֖ינַי אֶל־הֶֽהָרִ֑ים מֵ֜אַ֗יִן יָבֹ֥א עֶזְרִֽי:
A song for ascents: The simple meaning is that when the Levites began to ascend the steps, they recited this song. Although this song is not written first, there is no chronological sequence.) (In other books I found:  
A song for ascents: [The Psalmist] alludes, in the second psalm, to the steps that ascend for the righteous in the future from beneath the tree of life to the Throne of Glory, as we learned in Sifrei (Ekev 47): “It does not say here, ‘A song of ascents’ but, ‘A song for ascents’; a song for the One Who is destined to make ascents for the righteous in the future.” This is what the Kalir established (in the concluding poem of the morning service for the second day of Succoth, which was composed by Rabbi Elazar the son of Rabbi Simon the son of Yochai in Chagigah, chapter “We may not expound,” see there): “And from beneath them thirty steps, one above the other until the Throne of Glory, flying and ascending with the pleasant speech of the song of ascents.”  
2My help is from the Lord, the Maker of heaven and earth.   בעֶזְרִי מֵעִ֣ם יְהֹוָ֑ה עֹ֜שֵׂ֗ה שָׁמַ֥יִם וָאָֽרֶץ:
3He will not allow your foot to falter; Your Guardian will not slumber.   גאַל־יִתֵּ֣ן לַמּ֣וֹט רַגְלֶ֑ךָ אַל־יָ֜נ֗וּם שֹֽׁמְרֶֽךָ:
4Behold the Guardian of Israel will neither slumber nor sleep.   דהִנֵּ֚ה לֹ֣א יָ֖נוּם וְלֹ֣א יִישָׁ֑ן שׁ֜וֹמֵ֗ר יִשְׂרָאֵֽל:
5The Lord is your Guardian; the Lord is your shadow; [He is] by your right hand.   היְהֹוָ֥ה שֹֽׁמְרֶ֑ךָ יְהֹוָ֥ה צִ֜לְּךָ֗ עַל־יַ֥ד יְמִינֶֽךָ:
6By day, the sun will not smite you, nor will the moon at night.   ויוֹמָ֗ם הַשֶּׁ֥מֶשׁ לֹֽא־יַ֜כֶּ֗כָּה וְיָרֵ֥חַ בַּלָּֽיְלָה:
7The Lord will guard you from all evil; He will guard your soul.   זיְֽהֹוָ֗ה יִשְׁמָרְךָ֥ מִכָּל־רָ֑ע יִ֜שְׁמֹ֗ר אֶת־נַפְשֶֽׁךָ:
8The Lord will guard your going out and your coming in from now and to eternity.   חיְֽהֹוָ֗ה יִשְׁמָר־צֵֽאתְךָ֥ וּבוֹאֶ֑ךָ מֵֽ֜עַתָּ֗ה וְעַד־עוֹלָֽם:
