Passage
Indeed, on her children I will have no mercy; for they are children of unfaithfulness;
Indeed, on her children I will have no mercy; for they are children of unfaithfulness;
Hosea 2:2 Contend with your mother! Contend, for she is not my wife, neither am I her husband; and let her put away her prostitution from her face, and her adulteries from between her breasts;
Hosea 2:3 Lest I strip her naked, and make her bare as in the day that she was born, and make her like a wilderness, and set her like a dry land, and kill her with thirst.
Hosea 2:4 Indeed, on her children I will have no mercy; for they are children of unfaithfulness;
Hosea 2:5 For their mother has played the prostitute. She who conceived them has done shamefully; for she said, ‘I will go after my lovers, who give me my bread and my water, my wool and my flax, my oil and my drink.’
Hosea 2:6 Therefore behold, I will hedge up your way with thorns, and I will build a wall against her, that she can’t find her way.
The verse centers on "faith", "mercy", "indeed", "children", and "unfaithfulness". It is saying that the verse draws attention to "faith" and "mercy", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "Lest I strip her naked and make..." into verse 5's "For their mother has played the prostitute...", so "faith" and "mercy" belong inside that flow. In Hosea context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "faith" and "mercy" with trust shaped by these words, not by a vague optimism outside the passage.
