Vayechi – Hamalach Hagoeil IV

“May the angel who redeems me from all evil bless the lads, and may my name be declared upon them, and the names of my forefathers Abraham and Isaac, and may they proliferate abundantly like fish within the land.” (Genesis 48:16)

Jacob also hinted that mentioning the names of Ephraim and Menashe would have as positive an effect in the ears of God as has mentioning the names of the patriarchs themselves. This sentiment is expressed in Jeremiah 31:19, when the prophet exclaims that every time God merely hears the name Ephraim mentioned He recalls him with feelings of mercy and has pity on his plight. (Or Hachaim HaKadosh)
