"And he shall lay his hand and slaughter" (Leviticus 1:4-5): in the place where they lay on hands, they slaughter; slaughter follows immediately upon the laying-on of hands. Rav Huna said in the name of Rav: There are three things that must follow immediately one after another. Prayer must follow immediately upon the blessing of redemption; slaughter must follow immediately upon the laying-on of hands; and the blessing must follow immediately upon the washing of the hands. Abbaye said: Also, blessing in the work of their hands follows immediately upon the presence of a Torah scholar, as it is said, "I have observed the signs, and the LORD has blessed me on your account" (Genesis 30:27). If you wish, learn it from here: "And the LORD blessed the Egyptian's house" on Joseph's account (Genesis 39:5).
Three Acts That Must Follow Hard Upon One Another
Yalkut Shimoni on Torah 439:1
וְסָמַךְ וְשָׁחַט, בְּמָקוֹם שֶׁהֵן סוֹמְכִין שׁוֹחֲטִין, תֵּכֶף לִסְמִיכָה שְׁחִיטָה. אָמַר רַב הוּנָא אָמַר רַב שָׁלֹשׁ תְּכִיפוֹת הֵן תֵּכֶף לִגְאֻלָּה תְּפִלָּה תֵּכֶף לִסְמִיכָה שְׁחִיטָה תֵּכֶף לִנְטִילַת יָדַיִם בְּרָכָה אָמַר אַבַּיֵּי אַף תֵּכֶף לְתַלְמִיד חָכָם בְּרָכָה בְּמַעֲשֵׂה יְדֵיהֶם, שֶׁנֶּאֱמַר (בראשית ל, כז) "נִחַשְׁתִּי וַיְבָרְכֵנִי" וְגוֹ'. אִיבָּעִית אֵימָא מֵהָכָא (שם לט, ה) "וַיְבָרֶךְ ה' אֶת בֵּית הַמִּצְרִי" וְגוֹ'.
