I have become
This phrase indicates a transformation or change in state. The Hebrew root "הָיָה" (hayah) is often used to denote becoming or existing. In the context of this psalm, it suggests a shift from a previous condition to one of distress or isolation. This transformation can be seen as a reflection of the psalmist's internal struggle and the external circumstances that have led to this new, undesirable state. It serves as a reminder of the transient nature of human conditions and the need for reliance on God's unchanging nature.

like a bird
The imagery of a bird is significant in biblical literature, often symbolizing freedom, fragility, or isolation. The Hebrew word "צִפּוֹר" (tsippor) is a general term for small birds, which can evoke a sense of vulnerability. In this context, the psalmist likens himself to a bird, emphasizing his feelings of being small, exposed, and defenseless. This metaphor can also suggest a longing for freedom or escape from the current plight, much like a bird that desires to fly away from danger.

alone on a roof
The phrase "alone on a roof" paints a vivid picture of solitude and exposure. In ancient Near Eastern culture, roofs were flat and often used as places of retreat or solitude. The Hebrew word "גַּג" (gag) refers to a roof, and being alone on a roof suggests a sense of isolation from community and protection. This imagery underscores the psalmist's feeling of being cut off from others and exposed to the elements, both physically and emotionally. It reflects a deep sense of abandonment and the need for divine companionship and shelter. Historically, this could also allude to the practice of mourning or seeking God in solitude, as individuals would often retreat to rooftops to pray or lament.

Sparrow.--See Note, Psalm 84:3. Here render, like a lonely bird. Some MSS. read, "a wandering bird."
