Now therefore do not give your daughters to their sons, neither take their daughters for your sons, nor seek their peace or their prosperity for ever: that you may be strong, and eat the good of the land, and leave it for an inheritance to your children for ever.
For God gives to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he gives toil, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit.
