And now was an expression that speakers in this culture commonly used to introduce their main topic. Your language may have a comparable expression that you can use in your translation. You could also use plain language. The UST models one way to do that.

show YHWH (Some words not found in UHB: and=now show YHWH with,you(pl) kindness and,faithfulness and=also I show with,you(pl) the,good (the),this which/who done the,thing (the),this )

If your language does not use abstract nouns for the ideas of kindness and faithfulness, you could express the same idea in another way. Alternate translation: [may Yahweh treat you kindly and be faithful to you]
