וַיַּ֤רְא הָֽאֱלֹהִים֙ אֶֽת־מַ֣עֲשֵׂיהֶ֔ם כִּי־שָׁ֖בוּ מִדַּרְכָּ֣ם הָרָעָ֑ה וַיִּנָּ֣חֶם הָאֱלֹהִ֗ים עַל־הָרָעָ֛ה אֲשֶׁר־דִּבֶּ֥ר לַעֲשׂוֹת־לָהֶ֖ם וְלֹ֥א עָשָֽׂה׃
Nakita ng Diyos ang kanilang mga gawa, na sila'y tumalikod sa kanilang masamang landas; at nagbago ng pasya ang Diyos tungkol sa kapahamakang sinabi Niyang gagawin sa kanila, at hindi Niya ito ginawa.
Rashi
and God will relent—He will think about the evil to repent of it.
Ibn Ezra
"And God saw" - that they believed in him. And it [the people's belief] is like this [episode] in [Parshat] Yitro: "before God." (Shemot 18:12).
Malbim
God saw what they did: that is, at first when the people of Nineveh repented, they only regretted what they had done, but did not repent with acts that would rectify their past sins through [positive] action. But after the king's order, God saw through all of their acts that they had repented. They repented through [positive] actions by actually returning stolen items and those obtained unfairly, therefore [the verse says] "And God renounced the punishment," and [this is] despite [the fact] that they only repented for the sin of theft, [and] not for idol worship, [even] with [taking] all this [into account], since their decreed punishment had been sealed because of theft and they rectified this,"he did not carry out the evil"- that is, if the evil was prepared to come upon them in [the course of] nature, according to the system [of the universe], then it would come to them then as well, after that [which] they worshiped idols in Eden and were under [the control of the natural] system- God would not strip the nature [of the world with regards to reward and punishment] for idol worshipers! But since the evil was not destined to come them from the side of the nature [of the world], only God set in place for the future to do the evil through the punishment (?), and when they repented for the sin of theft he did not carry out [the evil], and left them to behave according to the nature the system.
