Quotation sobre Salmos 16:8

One should strengthen himself like a lion to get up in the morning to serve his Creator, so that it is he who awakens the dawn. Rem"a: At least, one should not delay beyond the time when the congregation prays (Tur). Rem"a: "I have set the Lord before me constantly" (Psalms 16:8); this is a major principle in the Torah and amongst the virtues of the righteous who walk before God. For a person's way of sitting, his movements and his dealings while he is alone in his house are not like his way of sitting, his movements and his dealings when he is before a great king; nor are his speech and free expression as much as he wants when he is with his household members and his relatives like his speech when in a royal audience. All the more so when one takes to heart that the Great King, the Holy One, Blessed Is He, Whose glory fills the earth, is standing over him and watching his actions, as it is stated: "'Will a man hide in concealment and I will not see him?' - the word of God" (Jeremiah 23:24), he immediately acquires fear and submission in dread of God, May He Be Blessed, and is ashamed of Him constantly (Guide for the Perplexed III 52). And one should not be ashamed because of people who mock him in his service of God, and should also go modestly. And when he lies on his bed he should know before Whom he lies, and as soon as he wakes up from sleep he should rise eagerly to the service of his Creator, May He Be Blessed and Exalted (Tur).

"I have set Hashem before me always."¹Psalms 16:8. This is a fundamental rule of the Torah and of the attributes of the righteous who walk before God. For we cannot compare a person's lifestyle, his activities and affairs when he is alone, to his lifestyle, and activities and affairs when he is before a great king. Similarly, his conversation and speech when he is amongst family or relatives, [cannot be compared] to what they would be in the presence of a king, because then he would certainly take special care that all his activities and conversations be refined and correct. How much more so when you contemplate that Hashem, the greatest of kings, the Holy One, blessed is He, Whose glory fills the entire world, stands above you and views your actions, as it is said: "If a person will hide in hidden places will I not see him? Says the word of Hashem, Do I not fill the heavens and the earth!"²Jeremiah 23:24. [Bearing this in mind] it is certain that you will immediately acquire a feeling of reverence and submissiveness for the awesomeness of Hashem, Blessed be He, and be ashamed [to sin] before Him.
