סְעָדֵ֥נִי וְאִוָּשֵׁ֑עָה וְאֶשְׁעָ֖ה בְחֻקֶּ֣יךָ תָמִֽיד׃
Sokonglah aku, maka aku akan diselamatkan, dan aku akan senantiasa menekuni ketetapan-ketetapan-Mu.
Ibn Ezra
"Who will show us good?" (מִי־יַרְאֵנוּ טוֹב - Mi yar'enu tov): [Regarding the next word, נְסָה - Nesah ("Bestow" / "Lift up")] Some say: That the word Nesah is from the verbs lacking the Lamed [final root letter] (alumei ha-lamed), [with the root being] נ-ס (N-S). And it properly should have been [formed] according to the pattern of [imperatives like] u-Re'eh ("and see!") and va-Aseh ("and do!"). And it appears in the form that it has [נְסָה, with the final Heh typical of this verb class], similar to (Psalm 119:117) "ve-esh'ah be-chukekha" ("and I will gaze upon Your statutes" - from root שעה). And it is correct [however] for the Heh [in נסה] to be like the Alef [of נשא - N-S-A, lift up], and the Samekh [in נסה] to be like the Shin [of נשא]. [Aside on verb types]: There are verbs called "lacking the Ayin" [middle root letter] (alumei ha-ayin), such as all the verbs [that appear to have only] two letters, like kam (קָם - arose) and shav (שָׁב - returned). And they are all as if one were to say [the imperatives] Kum! (קוּם) and Shuv! (שׁוּב), where the middle letter [Vav or Yod] is hidden (alumah), which corresponds to the Ayin [middle position] of the standard root pattern pa'al. [Returning to נסה]: And it is correct for the Heh to be like the Alef and the Samekh like the Shin, in the manner of (Numbers 6:26): "Yissa Ad-nai panav eilekha" ("May Ad-nai lift up His countenance upon you" - yissa from נשא), and like (Job 4:2): "Ha-nisah davar eilekha til'eh" ("If one attempts/lifts up a word to you, will you be weary?" - ha-nisah).
Rashi
ואל ישעו בדברי שקר AND LET THEM NOT REGARD VAIN WORDS — let them not think and speak always about “words of wind” saying, “Let us go and sacrifice”. Of similar meaning is, (Psalm 119:117) “And I will speak of (ואשעה ב־) thy statutes continually”. The phrase (Deuteronomy 28:37) למשל ולשנינה “[thou shalt become] a proverb and a byword” we translate in the Targum by “a topic of conversation (שועי)”, and the word ויספר (Genesis 24:66) “and he related” by ואשתעי “and he spoke about”. One cannot possibly say that the word ישעו has the same meaning as the verbs in (Genesis 4:4) “And the Lord turned (וישע) to Abel” and in (Genesis 4:4) “but to Cain and his offering he did not turn (שעה)”, and that we must translate אל ישעו by “Let them not turn”, for if this were so Scripture should have written אל דברי שקר or לדברי שקר (instead of בדברי) for so is the construction in all such cases. Examples are: (Isaiah 17:7) “A man shall turn to (ישעה אל) his Maker”; (Isaiah 17:8) “and he shall not turn to (ישעה על) the altars”; (Isaiah 31:1) “they turn not unto (שעו על) the Holy One of Israel”. I do not find the construction of a ב following these verbs in the sense of “turning to”, but after an expression of דבר “speaking” — as when one intently directs his conversation upon a matter — the construction with כ is quite an appropriate one. For instance: (Ezekiel 33:30) “those who intently direct their conversation (הנדברים) upon thee (בך)”; (Numbers 12:1) “And Miriam and Aaron directed their speech (ותדבר) upon Moses (במשה)”; (Zechariah 4:1) “And the angel who directed his conversaion (הדובר) upon me (בי)”; (Deuteronomy 11:9) “To turn your conversation (לדבר) intently upon them (בם)”; (Psalm 119:46) “And I will direct my speech (אדברה) upon thy testimonies (בעדותיך)”. So, too, here: ואל ישעו בדברי שקר means “let them not always be conversing about vain and idle matters”.
