A song of ascents. By David:
Oh, how good, how pleasant it is for brothers to live together in harmony.
It is like fragrant oil on the head that runs down over the beard,
over the beard of Aharon, and flows down on the collar of his robes.
It is like the dew of Hermon that settles on the mountains of Tziyon.
For it was there that Adonai ordained the blessing of everlasting life.
Complete Jewish Bible
How does the Word describe the unity and oneness among believers? This is what sets us apart, like the anointing oil on the holy servant of Adonai. Unity marks us like the oil of consecration that separated the high priest from all the people of Israel. It sparkles on your face. It permeates the clothing and perfumes the air around us with sweet fragrance wherever we go. It is noticeable and it touches people. It is sweet and gentle, but so grand it improves the entire landscape of the nation! It's origins are heavenly, like a mantle of glistening dew that falls from heaven and covers the mountains of the Lord with breathtaking majesty. Our unity and oneness is our greatest grace and beauty. It is the symbol of blessing God ordained for us to wear, just as a bride adorns herself with a wedding dress and covers herself with a veil. When we love one another and live in unity together, we are in the very center of God's will, proving that we belong to the Father, we speak the language of his heart, and we are adorned with eternal life. This is why Yeshua said, "BY THIS shall all men know that you have eternal life, if you love one another."
John 13:35
