'Acquire' in the Bible

So I am legally informing you: Acquire it before those sitting here and before the leaders of my people! If you want to exercise your right to redeem it, then do so. But if not, then tell me so I will know. For you possess the first option to redeem it; I am next in line after you." He replied, "I will redeem it."

Then Boaz said, "When you acquire the field from Naomi, you must also acquire Ruth the Moabite, the wife of our deceased relative, in order to preserve his family name by raising up a descendant who will inherit his property."

So the guardian said to Boaz, "You may acquire it," and he removed his sandal.
