The loins, as in Ezekiel 29:7, signify the marriage of truth and good. In general, loins signify love, and when referring to the Lord, divine love. They can also signify the interiors of conjugial love. In Isaiah 11:5, they signify people in the divine good of love, and reins signify people in love towards their neighbor.

Verses 1-5 And these are the names of the children of Israel who came to Egypt with Jacob - a man and his household they came: Reuben, Simeon, Levi, and Judah; Issachar, Zebulun, and Benjamin; Dan and Naphtali, Gad and Asher. And every soul, those who came out of Jacob's thigh, were seventy souls; and Joseph was in Egypt.
