Musar zu Bereschit 43:29

[When the merchant finished his discourse] Rabbi Yose and Rabbi Chiya came and kissed him upon the head, saying, “If we had not come into the world for any reason other than to hear this, it would have been enough for us. Fortunate is the generation of Rabbi Shimon ben Yochai in which wisdom can be found even amidst the mountains!” Then they inquired, “What is your name?” He responded, “Chanan.” So they blessed him with the verse, “May God give you grace [yachnecha], my son” (Bereishis 43:29), adding, “May God hear your voice whenever you need Him.”
