Galatia 4:4-5

4:4 But when the appropriate time ¹  had come, God sent out his Son, born of a woman, born under the law, 4:5 to redeem those who were under the law, so that we may be adopted as sons with full rights. ² 

Galatia 4:21

An Appeal from Allegory

4:21 Tell me, you who want to be under the law, do you not understand the law? ³ 

[4:4]  ¹ tn Grk “the fullness of time” (an idiom for the totality of a period of time, with the implication of proper completion; see L&N 67.69).

[4:5]  ² tn The Greek term υἱοθεσία (Juioqesia) was originally a legal technical term for adoption as a son with full rights of inheritance. BDAG 1024 s.v. notes, “a legal t.t. of ‘adoption’ of children, in our lit., i.e. in Paul, only in a transferred sense of a transcendent filial relationship between God and humans (with the legal aspect, not gender specificity, as major semantic component).” Although some modern translations remove the filial sense completely and render the term merely “adoption” (cf. NAB), the retention of this component of meaning was accomplished in the present translation by the phrase “as sons.”

[4:21]  ³ tn Or “will you not hear what the law says?” The Greek verb ἀκούω (akouw) means “hear, listen to,” but by figurative extension it can also mean “obey.” It can also refer to the process of comprehension that follows hearing, and that sense fits the context well here.
