'Advantageous' in the Bible

If you then, evil (sinful by nature) as you are, know how to give good and advantageous gifts to your children, how much more will your Father who is in heaven [perfect as He is] give what is good and advantageous to those who keep on asking Him.

but whoever causes one of these little ones who believe in Me to stumble and sin [by leading him away from My teaching], it would be better for him to have a heavy millstone [as large as one turned by a donkey] hung around his neck and to be drowned in the depth of the sea.
