The sense of the words in verses 50 and 51 is that Laban and Bethuel agree to the proposal that Rebekah should go back with the servant to be married to Isaac. In some languages it will be necessary to include at this point words such as “All right,” “It is good,” or “We-two agree.”
Behold, Rebekah is before you: Behold serves to point out the presence of Rebekah. Good News Translation translates “Here is Rebekah.”
Take her and go: more detail may need to be given to this; for example, “Take her with you and go back to Canaan.” In some languages this is expressed as “You lead her and you-two go back to your place.”
Let her be the wife: examples of how this may be expressed in translation are “She can marry your master’s son” and “It is good that she will be married to….”
As the LORD has spoken: spoken here means “decided,” “determined,” “arranged.” Revised English Bible and New Jerusalem Bible translate “as the LORD has decreed,” New International Version “as the LORD has directed,” Die Bibel im heutigen Deutsch “as the Lord has decided.” It is possible for the last part of the verse to be restructured; for example, “You take her back, because the LORD has shown you that she is the one who will be the wife of your master’s son.”
