New Testament

Matthew 7:5

3 Why do you see the speck in your brother’s eye, but fail to see the beam of wood in your own? 4 Or how can you say to your brother, ‘Let me remove the speck from your eye,’ while there is a beam in your own? 5 You hypocrite! First remove the beam from your own eye, and then you can see clearly to remove the speck from your brother’s eye. 6 Do not give what is holy to dogs or throw your pearls before pigs; otherwise they will trample them under their feet and turn around and tear you to pieces. 7 “Ask and it will be given to you; seek and you will find; knock and the door will be opened for you.

Bava Metzia 107b

Babylonian Talmud

The Gemara relates another incident: Rabba bar Rav Huna had a certain forest on the bank of a river. They said to him: Let the Master cut down the trees on the riverbank in accordance with the above statement. Rabba bar Rav Huna said to them: Let those above and below me along the river cut down their trees first, and then I will cut down my trees. I will achieve nothing by cutting down my trees on my own. The Gemara asks: How can he do so, i.e., wait for others to act? But isn’t it written: “Gather yourselves together, and gather [hitkosheshu vakoshu]” (Zephaniah 2:1), and Reish Lakish says concerning this: Adorn [keshot] yourself and afterward adorn others. Therefore, one must first perform the required action himself before offering advice to others.
