ל֗וּ עַ֭מִּי שֹׁמֵ֣עַֽ לִ֑י יִ֝שְׂרָאֵ֗ל בִּדְרָכַ֥י יְהַלֵּֽכוּ׃
Sekiranya umat-Ku mau mendengarkan Aku, dan Israel mau berjalan menurut jalan-jalan-Ku!
Rabbeinu Bahya
ויחל העם, “the people profaned themselves.” The word ויחל means to profane something which previously was sacred, holy. We encounter the same word in connection with Noach (Genesis 9,2), when Noach planted a vineyard and became drunk. Judaism describes people who are meticulous in their sexual mores as ”holy,” whereas those that are not are considered as “profane.” Whenever the Torah refers to the Israelites simply as העם, this term implies a criticism of their spiritual level (at that time). The Following are some examples of the Torah using this terminology: Numbers 11,1: “the people were looking for something to complain about.” Numbers 20,3: “the people quarrelled.” Numbers 21,5: “the people spoke out against G’d.” On the other hand, whenever the people of Israel are referred to as עמי, this is to be taken as a complimentary term; examples are: Psalms 81,14: “if only My people would listen to Me.” Exodus 7,4: “I will take out the hosts of My people.” Isaiah 40,1: “comfort, comfort My people.”

They hurried him. A miraculous deliverance always transpires with haste. So it was when the Israelites left Egypt (see Shemos 12:39), and so will it be when Yisrael is redeemed from the current exile.
Ibn Ezra
לוא קרעת שמים Some refer this phrase to the revelation on Mount Sinai, and render it As if Thou hadst not rent the heavens;1To give us Thy commandments. לוּא is, according to this explanation, the same as לא not. Comp. Targum Jonathan: לא להון ארבנת שמיא not for them (for the heathen people) hast thou descended from heaven. but it is more correct to take לוּ═לוּא in its usual meaning if; (comp. Ps. 84:13), and to explain the sentence thus: If Thou wouldst rend the heavens and come down, that is, if Thou wouldst send forth Thy decrees, then, the mountains, that is, the kings2Kingdoms (מלכות) or nations (גוים) would better correspond with the phrase מפניך גוים ירגזו thus the nations would tremble at Thy presence (64:1), which seems to be the explanation of מפניך הרים נזלו. who sit in safety, would flow down at Thy presence. נָזֹלּוּ Would flow down. The Dagesh in the ל is caused by the pause;3This Dagesh is called by the Grammarians: euphonic (לתפארת הקריאה); comp. חָדְלֽוּ ═ חָדֵלּֽוּ (Jud. 5:7).
