Luke 10:27

ἀγαπήσεις κύριον τὸν θεόν σου. This was the summary of the Law in Deuteronomy 6:5; Deuteronomy 10:12; Leviticus 19:18.

ἐν ὅλῃ τῇ διανοίᾳ σου. Only three substantives are used in the Hebrew and the LXX[226], but the latter translate לב, ‘heart,’ by διανοία, ‘understanding.’ St Mark also has the four substantives, but uses σύνεσις for διανοία. St Matthew has three (Luke 22:37). Godet.

[226] LXX. Septuagint.

καὶ τὸν πλησίον σου ὡς σεαυτόν. Hillel had given this part of the answer to an inquirer who similarly came to put him to the test, and as far as it went, it was a right answer (Romans 13:9; Galatians 5:13-14; James 2:8); but it became futile if left to stand alone, without the first Commandment.
