Matthew 6:34
31 So then, don’t worry saying, ‘What will we eat?’ or ‘What will we drink?’ or ‘What will we wear?’ 32 For the unconverted pursue these things, and your heavenly Father knows that you need them. 33 But above all pursue his kingdom and righteousness, and all these things will be given to you as well. 34 So then, do not worry about tomorrow, for tomorrow will worry about itself. Today has enough trouble of its own.
Sanhedrin 100b
Babylonian TalmudWe also teach what it states there: Avert your eyes from a woman of grace, lest you be trapped in her snare. Turn not to her husband to mix wine and strong drink with him, as many have been corrupted by the beauty of the beautiful woman, and mighty are all her fatalities (Ben Sira 9:9–11). Many are the wounds of a peddler (Ben Sira 11:36), which in this context is referring to those who accustom others to matters of forbidden sexual relations. Like a spark ignites a coal (Ben Sira 11:43), like a cage full of birds, so too, their houses are filled with deceit (Ben Sira 11:36–37). Prevent the multitudes from inside your house, and do not bring everyone into your house (Ben Sira 11:37). Let many be those who greet you; reveal your secrets to one in a thousand. From she who lies in your bosom guard the openings of your mouth, i.e., do not tell her everything. Grieve not about tomorrow’s trouble, because you know not what a day may bring; perhaps tomorrow you will no longer be, and one will have worried about a world that is not his.
