Adam Clarke on Acts 13:18

About the time of forty years - The space of time between their coming out of Egypt, and going into the promised land.

Suffered he their manners - Ετροποφορησεν αυτους; He dealt indulgently with them: howsoever they behaved towards him, he mercifully bore with, and kindly treated them. But instead of ετροποφορησεν, ACE, some others, with the Syriac, Arabic, Coptic, Ethiopic, and some of the fathers, read ετροφοφορησεν, which signifies, he nourished and fed them, or bore them about in his arms as a tender nurse does her child. This reading confirms the marginal conjecture, and agrees excellently with the scope of the place, and is a reading at least of equal value with that in the commonly received text. Griesbach has admitted it, and excluded the other. Both, when rightly understood, speak nearly the same sense; but the latter is the most expressive, and agrees best with Paul's discourse, and the history to which he alludes. See the same form of expression, Num 11:12; Exo 19:4; Isa 46:3, Isa 46:4; Isa 63:9.
