21. Come and behold, Isaac was with his wife for twenty years, but she did not give birth until he had said his prayer. This is because the Holy One, blessed be He, desires the prayer of the righteous, when they ask Him in prayer for their needs. Why? Because the anointing oil will be increased by the prayer of the righteous for all those in need of it. FOR THE RIGHTEOUS IN THEIR PRAYER OPEN THE SUPERNAL CHANNEL, AND THEN EVEN THE PRAYERS OF THE UNWORTHY ARE ANSWERED.
21. תָּא חֲזֵי, עֶשְׂרִין שְׁנִין, אִשְׁתָּהֵי יִצְחָק עִם אִתְּתֵיהּ, וְלָא אוֹלִידַת, עַד דְּצַלֵּי צְלוֹתֵיהּ בְּגִין דְּקוּדְשָׁא בְּרִיךְ הוּא אִתְרְעֵי בִּצְלוֹתְהוֹן דְּצַדִּיקַיָא, בְּשַׁעְתָּא דְּבָעָאן קַמֵּיהּ צְלוֹתְהוֹן, עַל מַה דְּאִצְטְרִיכוּ, מַאי טַעְמָא, בְּגִין דְּיִתְרַבֵּי וְיִתּוֹסַף רְבוּת קוּדְשָׁא, לְכָל מַאן דְּאִצְטְרִיךְ בִּצְלוֹתְהוֹן דְּצַדִּיקַיָּיא.
