Judges 3:2

only that the generations of the children of Israel might know, to teach them war, at least those who knew nothing of it before:

if only to teach warfare to the subsequent generations of Israel, especially to those who had not known it formerly:

Only that the generations of the children of Israel might know, to teach them war, at the least such as before knew nothing thereof;

only that the generations of the children of Israel might know, to teach them war, at the least such as beforetime knew nothing thereof:

Only because of the generations of the children of Israel, for the purpose of teaching them war--only those who up till then had no experience of it;
