12 And if you do obey these rules and observe them carefully, Hashem your God will maintain faithfully for you the covenant that He made on oath with your fathers:

יב וְהָיָה עֵקֶב תִּשְׁמְעוּן אֵת הַמִּשְׁפָּטִים הָאֵלֶּה וּשְׁמַרְתֶּם וַעֲשִׂיתֶם אֹתָם וְשָׁמַר יְהֹוָה אֱלֹהֶיךָ לְךָ אֶת־הַבְּרִית וְאֶת־הַחֶסֶד אֲשֶׁר נִשְׁבַּע לַאֲבֹתֶיךָ׃
7:12 And if you do obey these rules
In this verse, Hashem promises that if we listen to His commandments, He will bless us and multiply us, and grant us success in the Land of Israel. The Hebrew word for ‘and if you do,’ eikev (עקב), also means ‘heel.’ Rashi quotes the Sages who teach that the use of the word eikev hints to the fact that we must keep all the commandments equally, even the ones that seem unimportant, which people tend to figuratively step on with their heels. If we are careful to follow all the commandments of Hashem, even the seemingly insignificant ones, then we will certainly be rewarded with great blessings in the Promised Land.
