Halakhah zu Könige I 14:9

From the break of dawn, it is forbidden to eat or drink before praying. The Sages support their words (Berakhot 10b) on the verse (Vayikra 19:26), “Do not eat upon the blood,” which they interpret as, “Do not eat before praying for your ‘blood.’” Further, they teach, “Anyone who eats and drinks first and [only] afterwards prays, Scripture says of him (1 Melakhim 14:9), ‘You have thrown Me behind your body (“gavekha,” the word used for “your body,” alludes to “ga’avatekha” – your pride).’ God said, ‘After this person acts arrogantly he accepts upon himself the yoke of heaven?!’”

He who honors is honored,¹Aboth 4:8. he who honors the Holy One, blessed be He, and that which He commands, is honored by Him.²Midrash Tanhuma, ed. Horeb, Vayigash, p. 140. It is not proper that you put books on a bed which you slept upon lest there be semen on the bed or one broke wind in the bed, similarly it would not be proper that you hold between your legs or behind you holy writings, for it is said “And has cast Me behind they back” (I Kings 14:9). And it is not proper when a man has had intercourse in bed and the moisture of sperm is yet upon him that he mention any matter of holiness, prayer or Torah. Rather let him wash himself well with water that there not cleave to him even the smallest piece³Shulhan Arukh, “Orah Hayim” 76. Mogen Avraham, note 7. (of semen). We find two purifications for three commands,⁴The Perush states that the three commands are: to meditate on Torah; to pray; to speak to friends only of Godly matters. The two purifications are directives to abstain from the aforementioned commands when he finds himself in a place of filth or if his person is soiled with semen. “The words of the Lord are pure words” (Ps. 12:7). “But words of pleasantness are pure” (Prov. 15:26). This is to teach you that a man should not be in a place of filth and think of matters of Torah or pray,⁵Berakoth 24b. or speak to his friend of any matter concerning the Holy One, blessed be He, and neither (should he do so) when there is semen upon him. “The fear of the Lord is the beginning of knowledge, but the foolish despise wisdom and discipline” (Prov. 1:7). “For that they hated knowledge, and did not choose the fear of the Lord” (Prov. 1:29). “Then shalt thou understand the fear of the Lord, and find the knowledge of God” (Prov. 2:5).
