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.

6691. Verse 22 And Pharaoh commanded all his people, saying, Every son who is born you shall throw into the river, and every daughter you shall keep alive.

'And Pharaoh commanded all his people' means a general influx into factual knowledge opposed to the Church's truths. 'Saying, Every son who is born you are to throw into the river' means that all truths that appeared should be drowned in falsities. 'And every daughter you shall keep alive' means that they should not attack good.
