Lamentations 3:62, "the lips of those that rose up against me, and their plots against me all day long," speaks to the constant and malicious opposition the speaker is facing. Let's break it down:

"the lips of those that rose up against me": This refers to the hostile speech and accusations directed towards the speaker. It implies that the speaker is being actively attacked with words, potentially slander, mockery, or threats. "Rose up against me" indicates a sense of rebellion or defiance against the speaker.

"and their plots against me all day long": This highlights the relentlessness and intent behind the verbal attacks. "Plots" suggests that the opposition is not just spontaneous outbursts but carefully planned strategies to harm or undermine the speaker. "All day long" emphasizes the constant, unending nature of this harassment. There's no respite or peace for the speaker.

In essence, the verse conveys a sense of being surrounded by enemies who are constantly speaking out against the speaker and scheming to cause harm.

Context in Lamentations:

It's crucial to understand the context of Lamentations. The book is a lament over the destruction of Jerusalem and the suffering of its people following the Babylonian conquest. The speaker is often considered a personification of the city of Jerusalem or the people of Judah. Thus, the verse likely represents the enemies (Babylonians and perhaps internal factions) who are gloating over the city's downfall, plotting further harm, and spewing hateful words.

Possible Interpretations:

Literal: The verse could be interpreted literally as describing actual verbal attacks and conspiracies against the speaker.
Symbolic: It could also be symbolic of the spiritual and emotional attacks the speaker is enduring. The "plots" might represent feelings of hopelessness, despair, and the loss of faith.

Ultimately, the verse depicts a situation of intense pressure, hostility, and ongoing antagonism.
