Ephesians 6:8

6:8 because you know that each person, whether slave or free, if he does something good, this ¹  will be rewarded by the Lord.

Hebrews 6:10

6:10 For God is not unjust so as to forget your work and the love you have demonstrated for his name, in having served and continuing to serve the saints.

[6:8]  ¹ sn The pronoun “this” (τοῦτο, touto) stands first in its clause for emphasis, and stresses the fact that God will reward those, who in seeking him, do good.
