Charles Ellicott Commentary 2 Chronicles 7:17

"And as for thee, if thou wilt walk before me as David thy father walked, and do according to all that I have commanded thee, and wilt keep my statutes and mine ordinances;" — 2 Chronicles 7:17 (ASV)

Walked. — Kings adds, “in perfectness of heart, and in uprightness.” So Syriac and Arabic.

And do. — So Septuagint, Vulgate, and Arabic. The Hebrew is wĕ-la‘asôth, “ and to do,” a construction which the chronicler sometimes uses in continuation of a future (imperfect tense). But Kings has “to do,” an infinitive defining the former verb; and so the Syriac here.
