# Then I said

"Then I said to Yahweh". Nehemiah tells what he prayed. 

# Please, I beg you

These words translate one word with which the speaker calls for the attention of the hearer and indicates that the words that follow are a plea. If your language has another way of saying the same thing, you may want to use it here.

# Yahweh

This is the name of God that he revealed to his people in the Old Testament. 

# who love him and keep his commandments

"who love you and keep your commandments". Since Nehemiah is speaking to Yahweh, the pronouns "him" and "his" can be translated as "you" and "your".
