3121. 'And His truth towards my master' means an influx of charity from that inflowing love. This is clear from the meaning of 'truth' as charity. In the proper sense 'truth' means the same as faith, and in the Hebrew language faith is expressed by such a term, so that what is called truth in the Old Testament Word is regularly called faith in the New Testament Word. This is also why, in what has gone before, truth has often been called the truth of faith, and good the good of love. But in the internal sense faith is nothing else than charity - see what has often been stated and shown already, such as the following:

No faith exists except through love, 30-38.

Faith does not exist except where charity does so, 654, 724, 1162, 1176, 2261.

Faith is faith grounded in charity, 1608, 2049, 2116, 2343, 2349, 2417.

Charity constitutes the Church, not faith separated from charity, 809, 916, 1798, 1799, 1834, 1844, 2190, 2228, 2442.

From these paragraphs it is evident that in the internal sense truth or faith is the same as charity. Indeed all faith springs from charity, and faith that does not spring from it is not faith. Or what amounts to the same, all truth in the internal sense is good, since all truth is grounded in good, and truth that is not grounded in it is not truth. For truth is nothing else than the form that good takes, 3049; it is born from, and receives its life from nothing other than good.

“Washing” in the Bible represents purification - unsurprisingly! Washing dirt from the skin symbolizes using true ideas from the Lord to remove evil desires and false ideas from our minds. This is the reason that washing was such an integral part of ritual; cleaning the body to perform physical acts of worship - something with no actual spiritual value - is symbolic of repenting our evils and falsities as part of worshiping the Lord.
